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.

Can AI help limited information have endless potential?
By: Kelsey D. Atherton Humans are remarkably good at choosing to act on limited information. Computers, less so. A new DARPA program wants to train artificial intelligence to process and evaluate information like humans do, and produce actionable results on far smaller datasets than presently done. It's a program of such important DARPA's giving it VIP status, or a least VIP as an acronym: Virtual Intelligence Processing. “Successful integration of next-generation AI into DoD applications must be able to deal with incomplete, sparse and noisy data, as well as unexpected circumstances that might arise while solving real world problems,” reads a solicitation posted June 14. “Thus, there is need for new mathematical models for computing leading to AI algorithms that are efficient and robust, can learn new concepts with very few examples, and can guide the future development of novel hardware to support them.” To create these mathematical models, DARPA wants partners to look inward, creating AI inspired by the robust and massive parallelism seen in the human neocortex. If it is the architecture of the brain that makes humans so especially skilled at processing information quickly, then it is an architecture worth studying. “In order to reverse engineer the human brain,” the solicitation continues, calmly, “we need to apply new mathematical models for computing that are complete and transparent and can inform next-generation processors that are better suited for third-wave AI.” It is DARPA's nature to inject funding into problem areas it sees as both yielding future results and not presently served by the market, and this is not different. The solicitation explicitly asks for mathematical models that have not already been the focus of AI development. It's also looking for models that can inform the development of future hardware, rather than programs that can run on existing machines. DARPA is interested in how the hardware works in simulation, but wants partners to hold off on actually making the hardware for the model. So, the plan goes: create a mathematical model, inspired by brains, to process information on a small and limited data set, and then design it for hardware that doesn't exist yet. Easy as that sounds, the solicitation also asks proposers to talk about the limitations of the algorithms when applied to military tasks, and specifically limitations related to accuracy, data, computing power and robustness. Working from limited information is an expected future of military machines going forward. Between electronic warfare, denied environments and the very nature of battlefield events as rare and hard to record moments, doing more with on-board processing of limited data should enable greater autonomy. Even in the rare case where a weapon system transmits data back for algorithm refinement, that data set will be orders of magnitude smaller than the big data sets used to train most commercial machine learning tools. Should a proposer's idea be accepted and they follow through both Phase 1 and Phase 2 of the project, the total award is set at $1 million. A tidy sum, for anyone who can figure out the math to make a future computer run on sparse information as effectively as a human brain. https://www.c4isrnet.com/artificial-intelligence/2019/06/18/can-brain-inspired-ai-run-on-lean-data/

Opportunity knocks: A look at the used helicopter market
by Howard Slutsken If you're thinking of buying or selling a used helicopter, this might actually be a good time to do so. Maybe we're finally getting past our focus on the doldrums in the oil and gas sector, or it could be that the replacement cycle is catching up with older helicopters, with operators making the decision to upgrade their fleets. The helicopter market has always been very cyclical, and the perceived strength of the marketplace will often depend on the specific needs of a region — and the opinion of who you talk to. “The trend we're seeing in Canada is for hydroelectric powerline work, whether patrol or working on the towers, they're going with Cat A twin-engine aircraft,” said Steve Dettwiler, president of Maple Leaf Helicopters Canada, a brokerage service based in British Columbia. “Some operators are using the MD 902 Explorer, others the [Airbus] EC135. There are lots of [Airbus AS350] AStars available, but for Cat A [performance requirements], you'd have to go with an [Airbus] AS355NP TwinStar. “We're seeing the Bell LongRangers being sold off and replaced by the AS350 B2 and B3 series,” Dettwiler continued. “When it comes to the B3e [H125], most Canadian operators are interested in the ones that have dual hydraulics. For forest service work, there's the inclination to go to twin-engine on the Bell mediums.” Airbus machines are certainly in demand, and it might be a better financial and operational decision to search the used market rather than buy new, according to Jason Kmiecik, president of HeliValue$, producers of The Official Helicopter Blue Book. “The lights twins — EC135s, 145s — there's a big market for those,” he said. “In the U.S., Metro Aviation and Air Methods have pretty much grabbed everything [in terms of those types] that was for sale or is about to come online for sale. In today's market, you could buy two used aircraft, fully retrofit them with brand new interiors and avionics in both aircraft, and you're at about the price of one brand new aircraft. “There are plenty of transactions happening on those aircraft all over the place,” Kmiecik continued. “Some of them have actually started going up in value — the AStars and some of the newer 407s — because there's just starting to not be that many out there for sale.” Finding a deal But, as with any marketplace, there are bargains to be found. “There are some really good deals out there,” said Dettwiler. “As an example, we've got a Bell 212 for sale for $1.5 million, which is a good price for a 212. [The market] does go in cycles. Right now there are a lot of aircraft available for sale, which drives the prices down. You can get into a nice little JetRanger probably for $350,000 to $400,000.” There's also a bit of an underground marketplace where transactions happen quietly, with a handshake, explains Kmiecik. “You'll see the sales happen,” he said. “They were never listed online. They sell to the operator next door or somebody's buddy. The smaller, cheaper aircraft are garage transactions.” And speaking of those smaller machines, Kmiecik believes that the operators who still love Schweizer helicopters are going to be happy with the company's new owners, Schweizer RSG. “Their plans are to go full production again,” he said. “So I think there's going to be a comeback of Schweizer.” While Kevin Mawhinney, helicopter technical advisor at Jet Support Services, Inc. (JSSI), doesn't think much has changed in “the day-to-day, ins-and-outs of the industry,” he does see a trend developing in the “larger-medium” sector. “I think you're going to see more people move into this segment with machines that fill that niche,” he said. “For example, the [Leonardo] AW139 has really filled a need, and we're seeing a lot of interest in it.” He points to the multi-role capability of the AW139 as being a driver for new operators. “I think it fills a niche that no other machine was filling before.” Super Pumas airborne again And what about all of those Airbus H225 Super Pumas that have been languishing on helipads around the world? They're now in demand, according to Kmiecik — but for utility work, not offshore. “What we're seeing now is supply is actually shrinking,” he said. “Aircraft that were once for sale are now pulled off the market and are back to work with the original lessees or new people.” With the shift in deployment of Super Pumas from offshore work to utility missions, Kmiecik said that there's a bottleneck getting the parts that operators need to change the primary mission of their helicopters. “The 225 is becoming the utility machine, the go-to machine now,” he said. “The problem is the supply of utility parts with Airbus — cargo hooks and stuff like that. They can't get them in stock fast enough to ship out to the people who need them. There's aircraft waiting on the ground right now for parts so they can get out on a contract.” Kmiecik said that some operators have recognized the value in the 225 and have focused their acquisition strategy on the type. “It's a lot of aircraft with a lot of lifting for the price.” Dettwiler also knows of companies that targeted an opportunity by buying up inventory of specific types. “We sold 14 SA 315B Lamas in the past few years to a company in Scandinavia, who's basically stockpiling all the Lama inventory from around the world and supporting the existing Lama operators. But it's going to come to an end. Airbus would prefer to sell the H125/AS350 B3e,” he said. Operating costs Brandon Battles, vice-president, Conklin & de Decker, has been researching and analyzing helicopter operating costs for over 30 years. With his years of experience, Battles has seen the cyclical changes that the industry has faced. “I think we've all seen it through our careers - oil and gas is bad right now, but another operation that uses helicopters might be very strong,” he said. “The firefighting folks are probably having some pretty good years, from a business point of view. “I'm noticing now that it's not just the acquisition cost that's important anymore, it's also those operational costs that they'll be encountering over the long ownership of that aircraft,” he added. Kmiecik echoes that thought. “Pretty much everybody's complaint is to try to get operational costs cheaper for these aircraft, especially for the S-92,” he said. “It's a very expensive aircraft to operate, and with what they're making each month on their contracts, it's getting very tight to be able to make a profit at all on them.” While some of the focus on operational costs may be driven by corporate acquisitions and industry consolidation, Battles believes that operators at all levels have become more attuned to the business side of the equation, in some ways resulting from the economic downturn of 2008. He said that operators may have planned to acquire a helicopter and keep it for perhaps 10 years. After that, they may look to sell it to avoid major inspections or the required replacement of life-limited items or other significant maintenance. “They had a plan but when the economy changes and they can't sell the aircraft for as much as they planned, now they must continue to operate it and wrestle with some of the higher costs that are associated with an older aircraft,” said Battles. “Maybe because of that experience, people are considering the maintenance and operating costs more than they used to.” What's next? Kmiecik's analysis of the super-medium market suggests that machines like the Airbus H175, Leonardo AW189 and the upcoming Bell 525 are going to face challenges in making an impact on the market. “In general, the super-mediums haven't lived up to expectations that everybody thought was going to happen,” he explained. “And that's because the S-92 has dropped in value, so where it's actually cheaper to rent a S-92 than it is to buy a brand new super medium. “Capital is drying up in the space,” Kmiecik continued. “There's not many people that are willing to go out and buy a $15- to $35-million helicopter anymore for offshore when we've got so much supply still in the market right now that is sitting idle for sale.” And Kmiecik is pretty blunt in his assessment of what needs to happen in the oil sector to ensure that helicopter operators can continue to provide service. “I think over the next six months to a year, you're probably going to see some change in the attitude of the oil companies,” he said. “There has to be a change because they're forcing everybody into bankruptcy. I think that people are now telling them ‘no' on certain requirements that they're setting on tenders, like age requirements for aircraft. I think that they're going to have no choice but to start helping out the people who are keeping them in business.” https://www.skiesmag.com/features/opportunity-knocks-a-look-at-the-used-aircraft-market
