  Five Eyes Intel Alliance Urges Big Tech to Help Break Encrypted Messages

  By Joseph Marks The U.S. and four major allies warn new legislation might be necessary to ensure law enforcement can access communications. Homeland Security Secretary Kirstjen Nielsen joined leaders of the U.S.'s four major intelligence sharing partners Thursday in a statement urging tech companies to help law enforcement access otherwise-encrypted communications from criminals and terrorists. The joint statement stopped short of urging new laws to mandate that cooperation but warned that “should governments continue to encounter impediments to lawful access to information necessary to aid the protection of the citizens of our countries, we may pursue technological, enforcement, legislative or other measures to achieve lawful access solutions.” The statement from the U.S., Canada, the United Kingdom, Australia and New Zealand, collectively known as the Five Eyes, describes law enforcement's inability to access encrypted communications as “a pressing international concern that requires urgent, sustained attention.” While “governments should recognize that the nature of encryption is such that there will be situations where access to information is not possible,” the statement notes, “such situations should be rare.” Obama and Trump administration officials have warned since 2014 that end-to-end encryption systems, which shield the content of communications even from the communications provider, are allowing criminals and terrorists to plan operations outside law enforcement's reach. Legislative proposals that would make it easier for police to access those communications have failed to gain traction, however, even after a 2015 showdown between the FBI and Apple over an encrypted iPhone used by San Bernardino shooter Syed Farook. An inspector general's investigation in March found the FBI rushed to court in that case, seeking to compel Apple's assistance without exploring other options for cracking into the phone. Thursday's statement notes that: “Providers of information and communications technology and services ... are subject to the law, which can include requirements to assist authorities to lawfully access data, including the content of communications.” The statement does not go into detail, however, about what laws would justify those requirements and how they should be interpreted. The San Bernardino case was never decided in court because an unknown third party sold the FBI a method for breaking through the phone's passcode and accessing its encrypted contents. U.S. tech companies, for the most part, have resisted calls to cooperate with law enforcement. They argue that any effort to weaken encryption would be found and exploited by criminal hackers or foreign spies. Technologists, civil libertarians and many members of Congress have urged police to use other methods to break through encrypted communications without forcing companies to help or installing government backdoors into encryption systems. Those methods include obtaining a warrant to hack into the communications and building a case using unencrypted metadata. During the summit, Nielsen and other Five Eyes officials also agreed to strengthen cooperation between their nations' cyber centers and to cooperate on improving the cybersecurity of supply chains for critical infrastructure such as energy plants and airports. https://www.nextgov.com/cybersecurity/2018/08/five-eyes-intel-alliance-urges-big-tech-help-break-encrypted-messages/150961/

  Navigation systems that counter jamming and spoofing for Army vehicles, plus some goodies for the dismounted soldier

  By: Todd South Over the past few years, the Army's 2nd Cavalry Regiment in Germany has seen its Stryker combat vehicles up-gunned and upgraded with better firepower and stronger protection. A recent fielding amid follow-on efforts will give that regiment's soldiers and their supporting rotational brigade protection from invisible threats. That's because the Mounted Assured Position Navigation and Timing System, or MAPS, has been fielded to 62 Strykers in the regiment, with another 339 systems expected next year. Willie Nelson — the director of the Assured Positioning, Navigation and Timing Cross-Functional Team — and Col. Nickolas Kioutas — project manager for PNT — recently spoke with reporters about both the testing, development and fielding of MAPS and its dismounted version, known as DAPS. The two systems are key for soldiers to not only navigate but also use weapon systems and communications gear in heavily jammed and spoofing environments. Some of the most contested spaces with those challenges are in Europe. The first generation of the MAPS system has replaced then seven GPS antennas with just one, anti-jamming-capable GPS antenna that can distribute information across all systems in a vehicle, Kioutas said. That iteration has anti-jamming capabilities, a robust GPS receiver and a chip-scale atomic clock. The system has a seven-element array antenna. If it detects radio frequency energy from one direction that's attempting to jam a signal, then the array shuts off detection from that general direction but continues to scan the sky for the correct radio frequency signals to communicate. The clock keeps everything in time if the system is jammed for lengthy periods, Nelson said. The other threat, spoofing, involves an adversary introducing a decoy-type signal. Researchers are working on a capability for the next generation of MAPS that provides both anti-jam and anti-spoof capabilities. Testing that capability is scheduled for next year, with fielding expected by 2021. Even as the first generation is used by troops, the Army can continue to upgrade the system with new capabilities as it comes off the production line. Army leaders will decide next year if the fully fielded MAPS gear will serve as its first generation with upgrades, or a revamped, second variant, Nelson said. And it's not just for Strykers. The next wave of fielding will go to Bradley Infantry Fighting Vehicles, Paladin howitzers and Abrams tanks, which provide the firepower enabled by cavalry formations. And the focus will be to first provide 2nd CR and then the rotational brigade that heads to Europe each year, Kioutas said. Ultimately, a focused fielding plan will see 20,000 Army vehicles with the new MAPS onboard by 2028, officials said. For the individual soldiers, the same groups are working on the dismounted version. DAPS does not have an anti-jam capability yet, but it does use the new GPS M-Code signal that has more complicated encryption. DAPS will replace the existing antenna for the Nett Warrior system, and it is lighter and more effective, Kioutas said. Nett Warrior is an Android smartphone-based navigation, friendly forces and battlefield chat tool that will connect into the Integrated Visual Augmentation System, a mixed reality goggle expected to tie in communications, navigation, targeting and night vision into an individual soldier's heads-up display. https://www.armytimes.com/news/your-army/2019/10/18/navigation-systems-that-counter-jamming-and-spoofing-for-army-vehicles-plus-some-goodies-for-the-dismounted-soldier/
