Chiffrement : la NSA plaide pour un cadre légal d’accès aux communications


25 février 2015 Jacques Cheminat - silicon.fr


Mike Rogers, directeur de la NSA, rejoint la plainte de son homologue du FBI contre la décision de chiffrer les communications de bout en bout par les géants de l’IT. Sans parler de backdoor, il plaide pour la mise en place d’un cadre légal.


C’est toujours un exercice difficile de parler devant un public qui n’est pas acquis à votre cause. Mike Rogers, directeur de la NSA et en charge du cyber commandement américain s’est donc plié à cet exercice lors de la conférence Cybersecurity for a new America à Washington. Dès le début de son entretien, il plaide pour la création d’un cadre légal en dehors du contrôle de la NSA et du FBI pour fixer les règles en matière de renseignement aux Etats-Unis et en dehors. Un outillage juridique rendu nécessaire par l’augmentation des risques et des menaces. « Chaque année nous perdons entre 100 et 400 milliards de dollars par le vol de propriété intellectuelle avec un intérêt particulier pour le département de la Défense », précise le dirigeant. Aujourd’hui, il avoue que la cyberdéfense américaine n’est pas mature sans ce corpus législatif qui encadre les renseignements, la dissuasion et les niveaux de ripostes.

Dans son intervention, il est revenu sur un problème récurrent qui crispe les agences de renseignements, le chiffrement des communications. Avec l’affaire Snowden, de plus en plus d’acteurs de l’IT, Google, Apple, Facebook ou Yahoo ont mis en place des solutions pour chiffrer les échanges de leurs clients. James Comey, directeur du FBI, s’est fâché récemment contre cette stratégie et a demandé la mise en place de portes dérobées légales pour mener à bien les écoutes. Mike Rogers est plus diplomate sur le sujet.

13 November 2014 naval-technology.com


The Royal Australian Navy's (RAN) communications and information systems department has installed the computer network and communications suite on the Nuship Canberra, the first of two landing helicopter dock (LHD) vessels.


Since installation, the crew have been assessing the system in a bid to maintain its operational ability before the vessel's scheduled commissioning on 28 November.


In addition to offering enhanced potential for defence, the new system will enable the embarked forces and their headquarters staff to operate and communicate from the vessel.


Nuship Canberra communications and information warfare officer lieutenant commander Andrew Mannion said: "The planning for setting up the networks and communications systems onboard commenced early in the year.


"The communications suite on Canberra is significantly larger than any other ship in the fleet. We have approximately three times the amount of radios, networks and users."


Approximately 34 personnel from the department will operate the vessel's six local area networks (LANs) and offer 24/7 information technology (IT) helpdesk and information management, in addition to overseeing the radio, satellite and visual signalling communications mediums.


Around 50GB of data, including the ship's administrative paperwork and processes, has been migrated to the system and log-ons have been created for all 400 crew members, together with additional accounts on the classified networks.


Mannion added: "We had to transfer data that we had accumulated over the past 18 months to the ship's servers.


"When we start embarking forces, we will need to go through the same process for them, which could be approximately 300 additional personnel."


The vessel is also equipped with three internet cafés that allow crew to perform personal administration.


Work is still underway on the installation of a Wi-Fi network, which will enable crew and embarked forces to use personal devices to communicate with family and friends at home.

1 May 2014 Ministry of Defence and Defence Equipment and Support


More than a hundred jobs in south Wales are being sustained by a £364 million investment in military communications.


The Ministry of Defence has awarded two 5-year contracts to General Dynamics UK to support the Bowman radio system used by UK armed forces personnel.

General Dynamics UK will provide design, engineering and logistic support for the radio system that is used by service personnel across the British Army, Royal Navy and Royal Air Force.

The work will sustain the jobs of 140 highly skilled engineers at General Dynamics UK’s site in Blackwood near Newport in south Wales, with further roles being secured in the company’s wider supply chain.

Minister for Defence Equipment, Support and Technology Philip Dunne said:

For more than a decade, Bowman radios have played a vital role on operations, helping our personnel communicate sensitive information.

I am delighted that these significant contracts will protect 140 skilled engineering jobs in south Wales, allow us to deliver better value for money for the taxpayer, and, most importantly, ensure personnel on operations have the secure equipment they need.

This is more good news for south Wales ahead of the Nato summit later this year.

Bowman radios allow personnel on land, at sea and in the air to communicate on operations around the world. The radios use an encrypted frequency to share intelligence and increase situational awareness and have seen extensive service in Afghanistan by troops on patrol, on Royal Navy ships during relief efforts in the Philippines, and by the Royal Air Force when providing air support to land operations.

Chief Operating Officer of General Dynamics UK Steve Rowbotham said:

With our proven supply chain and support infrastructure, General Dynamics UK is uniquely placed to successfully deliver these contracts in parallel and ensure that the British armed forces have the security of supply and support as they continue to meet operational requirements around the world.

We are delighted to be able to continue with the successful partnership that has delivered world-class secure tactical communications to the British armed forces, building on this unique UK sovereign capability.

The new contract will see improved management of the radios and repair services. It will also allow competition within the supply chain to be opened up which is expected to deliver better value for money for the taxpayer.

Remote Troops Closer to Having High-Speed Wireless Networks Mounted on UAVs

Apr 08, 2014  (SPX)


Washington DC - Missions in remote, forward operating locations often suffer from a lack of connectivity to tactical operation centers and access to valuable intelligence, surveillance, and reconnaissance (ISR) data. The assets needed for long-range, high-bandwidth communications capabilities are often unavailable to lower echelons due to theater-wide mission priorities.

DARPA's Mobile Hotspots program aims to help overcome this challenge by developing a reliable, on-demand capability for establishing long-range, high-capacity reachback that is organic to tactical units.

The program is building and demonstrating a scalable, mobile millimeter-wave communications backhaul network mounted on small unmanned aerial vehicles (UAVs) and providing a 1 Gb/s capacity. DARPA performers recently completed the first of three phases in which they developed and tested key technologies to be integrated into a complete system and flight tested in subsequent phases.

"We're pleased with the technical achievements we've seen so far in steerable millimeter-wave antennas and millimeter-wave amplifier technology," said Dick Ridgway, DARPA program manager. "These successes-and the novel networking approaches needed to maintain these high-capacity links-are key to providing forward deployed units with the same high-capacity connectivity we all enjoy over our 4G cell-phone networks."


Phase 1 accomplishments include:

+ Smaller, steerable millimeter-wave antennas: During field testing, the program successfully demonstrated steerable, compact millimeter-wave antennas that rapidly acquire, track, and establish a communications link between moving platforms. Steerable millimeter-wave antennas will enable the formation of a high-capacity backhaul network between aerial and ground platforms.

+ Low-noise amplifiers: Performers also demonstrated an advanced low-noise amplifier (LNA), which boosts the desired communications signal while minimizing unwanted noise. The prototype achieved the record for the world's lowest noise millimeter-wave LNA at about half the noise figure of a typical LNA.

+ More efficient and capable power amplifiers: Efficient millimeter-wave amplification is required to achieve the long ranges (> 50 km) desired in the Mobile Hotspots program. During Phase 1, performers demonstrated output power exceeding 1 watt and 20% power added efficiency (PAE) from a single gallium nitride (GaN) chip operating at E-Band frequencies (71 GHz to 86 GHz). Output powers exceeding 20 watts and approaching 20% PAE were also achieved using power-combining techniques.

+ New approaches for robust airborne networking: Mobile ad-hoc networking approaches were developed to maintain the high-capacity backhaul network among mobile air and ground platforms. Phase 1 performers developed unique solutions to overcome connectivity and network topology challenges associated with mobility and signal blockages due to terrain and platform shadowing.

+ Low-Size, Weight, and Power (SWAP) pod design to carry it all: Performers created engineering designs for small, lightweight pods to be mounted on an RQ-7 Shadow UAV. The pods, with all of the Mobile Hotspots components inside, are designed to meet the challenging program goals of widths no more than 8 inches, weight less than 20 pounds, and power consumption less than 150 watts.


Phase 2 of the program began March 2014. Two performers, L-3 Communications and

FIRST RF, were chosen to lead teams comprising several Phase 1 performers. Phase 2 goals include the integration of the selected Phase 1 technologies into Shadow-compatible aerial pods and ground vehicles.

Phase 2 will conclude with a ground demonstration of at least four Shadow-compatible pods, two ground vehicles and a fixed ground node. A planned third phase will encompass field testing of the Mobile Hotspot systems on networks of multiple SRQ-7 Shadow UAVs and mobile ground vehicles.

U.S. Department of Defense Awards Iridium Contract for Iridium Airtime Services


Oct 30, 2013 (SPX)


McLean VA - Iridium Communications has been awarded a $400 million, multi-year, fixed-price contract with the Defense Information Systems Agency (DISA) to provide satellite airtime services to meet the communications needs of the U.S. Department of Defense (DoD) and their federal partners. This five-year contract renews the provision for delivering Enhanced Mobile Satellite Services (EMSS) airtime effective October 22.


Iridium will provide unlimited global secure and unsecure voice, low and high-speed data, paging and Distributed Tactical Communications System (DTCS) services for an unlimited number of DoD and other federal government subscribers.


The renewed EMSS contract extends the U.S. Government's (USG) existing relationship with Iridium and ensures the continuation of service through new terms which offer program stability and the best value to the DoD to expand services supporting its critical missions.


Both the multi-year and fixed-cost terms allow an even greater number of government subscribers to fully take advantage of the current capabilities as well as the enhanced services that will become available with Iridium NEXT -- the Company's next generation satellite constellation scheduled for first launch in early 2015 - without concern for incremental cost increases based on usage changes or growth in demand.


The Company's U.S. Government service revenue for the full-year 2012 was $61.8 million. The EMSS fixed-price rate in each of the five contract years is $64 million in fiscal year (FY) 2014, $72 million in FY 2015 and $88 million in FY 2016, 2017, and 2018.


"Iridium is proud to continue its longstanding relationship of providing global, mobile communications to the Department of Defense, our largest single customer," said Scott Scheimreif, Iridium's executive vice president, government programs.


"We expect the DoD's needs for satellite communication services will continue to grow over the next 5 to 10 years. At a time when the U.S. Government is operating under greater fiscal constraints, Iridium is confident that both our service and contract terms will provide an optimal solution for our warfighters and other federal partners to communicate effectively now and in the future."


In 2012, USG services and support made up 20 percent of Iridium's revenues. USG subscribers on the Iridium network have grown from 32,000 to over 51,000 during the last five-year contract period as services grew from basic voice and paging, to data and Netted Iridium with growing applications across all the services.


According to the Defense Business Board fiscal year 2013 report to the Secretary of Defense, commercial satellite communications currently supports about 40 percent of the DoD's satellite communication needs. Northern Sky Research (NSR), a global leader providing satellite industry market research, predicts this requirement will grow by 68 percent over the next decade.


The report concludes: "SATCOM is critical to supporting the warfighter, and DoD will require additional capacity in the future as new missions evolve and communication technologies further develop. To meet DoD's needs, the commercial satellite sector is a cost-effective source for obtaining technologically advanced services."


Iridium operates the world's largest commercial satellite network offering coverage anywhere in the world, including the polar regions. The Iridium NEXT program is a $3 billion investment to upgrade the network through the launch of 66 low-Earth orbiting (LEO) satellites, six in-orbit spares and nine ground spares, which will extend Iridium's position as a critical communications provider by offering substantially greater bandwidth, improved data speeds and continued global coverage to more than 275 government and commercial partners and consumers.


Iridium NEXT will also serve as a platform for AireonSM, a global aircraft-monitoring service using a space-based ADS-B hosted payload, as well as for the Company's newly announced Iridium PRIMESM offering, a turnkey solution for hosted payloads which will service all elements of a successful hosted payload mission at an estimated cost savings of 50 percent or more compared to current stand-alone solutions.

Bombardier Global Express Aircraft Configured as a BACN Aircraft, August 2007

Bombardier Global Express Aircraft Configured as a BACN Aircraft, August 2007

Sept. 17, 2013 by Dave Majumdar - FG


Northrop Grumman and Bombardier are set to deliver the last of four Battlefield Airborne Communications Node (BACN) aircraft to the US Air Force.


“There is going to be an official delivery ceremony in the coming weeks,” says Ben Boehm, Bombardier’s vice-president for sales and marketing. “It’s kinda up to the air force when they want to have the ceremony. The airplane is actually ready to go.”


The BACN, which will be used to facilitate communications between disparate US airborne assets, has been in development by Northrop since 2005. The idea was to use the communications node to translate data transmitted from stealthy fifth-generation fighters such as the Lockheed Martin F-22 Raptor and F-35 Joint Strike Fighter into a format usable by fourth-generation aircraft such as the Boeing F-15 Eagle and vice versa.


Originally, BACN was tested on board a NASA-operated Martin WB-57 Canberra bomber. However, a later prototype was installed on a Bombardier BD-700 business jet in 2011, which was ultimately designated as the E-11A.


After the success of the original E-11A prototype, which is being retained by the USAF, the service ordered three additional production aircraft based on the Bombardier Global Express 6000. It is the last of those three aircraft that is set to be delivered, Boehm says.


Boehm says that the USAF might order five more BACN II aircraft that would be somewhat modified from the current jets. Sensors, he says, are constantly evolving.


Bombardier says that further opportunities in the US market might arise from a programme to replace the USAF’s aging fleet of Northrop E-8 Joint Surveillance Target Attack Radar System aircraft. Service leaders, however, have said previously that while a business jet-derived JSTARS replacement is desirable, the USAF does not have the money to purchase such an aircraft.


Bombardier also hopes to leverage its new CSeries airframe for the military market, Boehm says. Two potential customers have already expressed interest in an airborne early warning platform based on the new aircraft.

Affaire Snowden : comment la NSA déjoue le chiffrement des communications

06.09.2013 Le Monde.fr


Les désormais célèbres documents d'Edward Snowden, l'ancien consultant de l'Agence de sécurité nationale (NSA), viennent d'éclaircir une facette encore obscure du gigantesque système de surveillance des télécommunications mis en place par les renseignements américains et britanniques.

Des articles publiés jeudi 5 septembre par le Guardian britannique, le New York Times américain et le site d'information sans but lucratif Propublica révèlent que la NSA et son alliée britannique, le GHCQ (Government Communications Headquarters), ont développé toutes sortes de méthodes pour contourner ou déjouer les méthodes de chiffrement censées protéger la confidentialité des données circulant sur Internet.

Des techniques qui "compromettent largement les garanties avancées par les entreprises d'Internet sur la protection des informations de leurs utilisateurs", qu'il s'agisse de transactions bancaires, de communications personnelles ou d'informations médicales, écrit le Guardian.



Les documents d'Edward Snowden révèlent que la NSA a mis en place depuis une dizaine d'années un programme baptisé "Bullrun", consacré à la lutte contre les techniques de chiffrement des communications, largement généralisées depuis 2010, qu'elle considère comme le plus grand obstacle à son "accès sans restriction au cyberespace". En témoigne la prière de ne pas publier ces informations adressée par le renseignement américain aux trois organes de presse, au risque que des "cibles étrangères" ne migrent vers de nouvelles formes de chiffrement qui seraient plus difficiles à contourner.

Le programme Bullrun aurait conduit en 2010 à une percée technologique exceptionnelle, qui aurait permis à la NSA de rendre "exploitables" de "vastes quantités" de données interceptées grâce à des écoutes de câbles Internet, ce que leurs propriétaires ont toujours démenti. Le GCHQ, avec un programme parallèle baptisé "Edgehill", aurait ainsi pu déchiffrer le trafic des "quatre grands" d'Internet : Hotmail, Google, Yahoo! et Facebook.

Des documents mentionnent également l'accès prochain, dès 2013, aux données d'un "opérateur majeur de télécommunications", ainsi que d'un "service de communications de pair à pair de premier plan", qui pourrait être Skype.

Selon le Guardian, l'agence américaine consacre 250 millions de dollars (190 millions d'euros) par an à travailler avec les entreprises technologiques pour "influencer secrètement" la conception de leurs produits. L'objectif : insérer dans les systèmes de chiffrement des vulnérabilités, ou "back doors", que la NSA pourra ensuite exploiter pour espionner les données.

L'agence influerait également sur la définition des standards mondiaux de chiffrement pour les détourner à son avantage, et utiliserait à l'occasion la "force brute" pour casser le chiffrement avec des superordinateurs, capables de tester toutes les clés de déchiffrage possibles grâce à des capacités de calcul gigantesques.

Si la cryptographie constitue "la base de la confiance en ligne", et de la structure même d'Internet, comme l'explique au Guardian Bruce Schneier, un spécialiste du domaine, la NSA considère les techniques de déchiffrement comme vitales pour mener à bien ses missions d'antiterrorisme et de renseignement extérieur. Des technologies réputées fiables, comme le HTTPS ou le SSL, qui protègent notamment les transactions en ligne, auraient ainsi cédé à l'effort américano-britannique. Mais comme le rappelait Edward Snowden en juin, certains systèmes de chiffrement plus solides résistent encore.

Avec ces révélations, il n'est donc plus question pour le complexe de renseignement américano-britannique de collecter les seules métadonnées (informations secondaires des communications, comme le nom du destinataire d'un courriel ou l'heure d'envoi), mais bien le contenu des communications, qu'on croyait jusqu'alors protégé par les systèmes de chiffrement.

Pour se défendre, la direction américaine du renseignement a rappelé que le décryptage des systèmes de chiffrement était la mission première de la NSA, et même le motif de sa création, en 1952. "Que la mission de la NSA soit de déchiffrer les communications cryptées n'est pas un secret [...]. Notre communauté du renseignement ne ferait pas son travail si nous ne tentions pas de contrer cela." L'agence avait pourtant jusqu'à présent assurer que ses programmes de cybersurveillance se limitaient pour l'essentiel à l'extraction des métadonnées, le contenu des messages lui demeurant inaccessible.

USAF B-2 Stealth Communications Systems Upgrade

06/09/2013 by Paul Fiddian - Armed Forces International's Lead Reporter


20 years overdue, the USAF B-2 Spirit communications upgrade programme is finally set to begin.


Right now, USAF Northrop B-2 Stealth Bombers receive presidential force instructions via ultra-high frequency communications systems, enabled by MILSTAR (Military Strategic Tactical and Relay) satellites. These satellites, though, are rapidly approaching their scheduled retirement date. Therefore, a programme named CVR Increment 1 is set to be introduced.


CVR (Common Very Low Frequency Receiver) will supply USAF B-2 pilots with "another, more reliable means to receive presidential force direction via emergency action messages", according to Gary Doolittle from the USAF's Global Strike Command.


Upgraded Stealth Communications


With this upgraded stealth communications system activated, the USAF's B-2s would receive signals without the need for the MILSTAR satellite fleet. Thus, the Air Force's Stealth capability would remain formidable while a MILSTAR replacement could be conceived, developed and pressed into service.


CVR Increment 1 took a significant step forward two months ago, when Engineering and Manufacturing Development Phase approval was granted. So, before too long, CVR Increment 1-based B-2 flight trials should be launched.


USAF officials make the point that, while CVR Increment 1 is B-2-optimised, the system could be adapted for other types of aircraft in US military service. These types could include the B-52 Stratofortress strategic heavy bomber, introduced in 1955 but set to remain with the USAF into the 2040s.


B-2 Communications Upgrade


USAF officials now expect that CVR Increment 1 communication systems will start to be operationally deployed on B-2s from 2017 onwards.


The B-2 Spirit ‘Stealth Bomber' and the B-52H Stratofortress are both part of the USAF's Global Strike Command. The USAF B-2 fleet has been extensively deployed on operations including Operation Odyssey - the 2011 sorties over Libya.


Introduced to the world in 1988, the B-2 Spirit is a dedicated low-observable strike platform. Its overall shape is intended to minimise its presence on enemy radar screens, allowing it to then deliver nuclear or conventional weapons after penetrating thick anti-aircraft defences.

TeleCommunication Systems (TCS) has secured incremental funding for the delivery of secret internet protocol router and non-secure internet protocol router access point (SNAP) tactical transportable TROPO (3T) deployable communications systems to the US Army.


The $2.8m funding is being provided by the US Army project manager for the warfighter information network-tactical (PM WIN-T) commercial satellite terminal programme, through the army's $5bn worldwide satellite systems (WWSS) contract vehicle.


TCS government solutions group-president, Michael Bristol, said the presence of cost-effective, easily deployable and reliable communications systems is vital to successful completion of the US military operations.


''TCS' JF-12 certified 3T fits these requirements, is a viable alternative to expensive satellite bandwidth, and its approved frequency assignment allows rapid access to global communication networks," Bristol said.

"The presence of cost-effective, easily deployable and reliable communications systems is vital to the US military operations."


3T is a high capacity, modular communications system designed to provide high bandwidth, low latency, non-satellite beyond line of sight (BLOS) network transport for both current and future bandwidth intensive command, control, communications, computers, combat systems, intelligence, surveillance and reconnaissance (C5ISR) platforms at distances of up to 150m.


Featuring the company's combat proven SNAP VSAT system and Comtech Systems' modem, the JF-12 certified system can offer long haul communications even in absence of bandwidth and over-the-horizon communications, in the regions where line-of-sight (LOS) is obstructed.


In addition, the Quad Diversity capable system establishes connectivity at greater data rates than typical satellite links, delivering greater speed for bandwidth-intensive applications, including intelligence, surveillance and reconnaissance (ISR) video distribution, without recurring satellite airtime costs.


Available on the TCS' SNAP 2.0M antenna, 3T also supports backwards compatibility with multiple US Department of Defense's (DoD) existing TROPO systems, such as AN/TRC-170 (V)2 and (V)3 systems.


The number of units ordered under the contract and delivery schedule has not been disclosed.

The US Army is implementing a new preventative maintenance concept, called condition-based maintenance plus (CBM+), in an effort to enhance efficiencies and reliability of its tactical communications network systems.


Implementation by the product manager for Warfighter Information Network-Tactical Increment 3 (PdM WIN-T Increment 3) follows a recent study, which confirmed the concept's ability to enhance system performance, while delivering a six-to-one return on investment.


WIN-T Increment 3 product manager lieutenant colonel Ward Roberts said the approach was designed to increase equipment performance, while simultaneously decreasing maintenance and support footprints.


"Considering that the bulk of a programme's costs are in logistics and sustainment, we see CBM+ as an opportunity to increase efficiencies, not only for our program, but for other army programmes as well," Roberts added.


Already pursued by the army for its aviation fleet, CBM+ strategy is focused on improving diagnostics and anticipatory maintenance, compared with the legacy reactive maintenance, and is also capable of offering error codes to highlight an impending problem to soldiers, preventing a system failure.


The existing network management software (NMS) used by WIN-T Increment 1 and WIN-T Increment 2, alerts soldiers only after equipment failure.

"Considering that the bulk of a programme's costs are in logistics and sustainment, we see CBM+ as an opportunity to increase efficiencies, not only for our program, but for other army programmes as well."


In addition, CBM+ can order required parts on forward operating bases (FOBs) and send them back to the unit, as opposed to common practice, which involves equipment swapped with spares if the failure cause is unclear, and subsequent transfer to depot, often resulting in unncecessary wastage, costs and time.


The concept also facilitates work on an as-needed basis by providing alerts when the equipment reaches a certain threshold of operation set on the system's sensors, generating significant maintenance time and cost savings for the army.


Implementation is scheduled to be carried out in increments called spirals, with spiral 1 focused on WIN-T Increment 3's advanced network operations capabilities, followed by its scheduled developmental testing in 2015 and limited user testing in 2016.


Spiral 1 will assist signal officers in network management, while Spiral 2 will focus on external interfaces to the army logistics systems.
