WASHINGTON: DARPA has launched a four-year project to find ways to design security features into microchips as they are being made to help ensure the future supply chain.
While the name of the project is daunting — Automatic Implementation of Secure Silicon (AISS) — and the technical requirements are a serious challenge, the concept is pretty simple.
“AISS aims to automate the process of incorporating security into chip designs, making it easier and potentially more cost effective for any organization with even a small design team (start-ups, mid-size companies, etc.) to build security measures into their designs,” a DARPA spokesperson told Breaking D today.
“Overall, with AISS DARPA aims to bring greater automation to the chip design process to profoundly decrease the burden of including security measures,” the spokesperson said.
The two winning teams, according to a May 27 DARPA press release, are:
The two AISS research teams are:
“Research and development on the $75 million program was commenced two weeks ago and incremental capabilities are expected to roll out to the chip design community over the next four years,” the spokesperson said in an email. “Our hope is that many of the capabilities will start appearing as features in commercial design automation software before the program completion.”
Digital integrated circuits are the engines that drive modern computers, and everyday digital devices such as smart phones. They are critical to the evolution of the Internet of Things (IoT). As such, they increasingly have become a key target of hacking by US adversaries and cyber criminals alike, DARPA explains.
“Threats to IC chips are well known, and despite various measures designed to mitigate them, hardware developers have largely been slow to implement security solutions due to limited expertise, high cost and complexity,” the DARPA release says. “Further, when unsecure circuits are used in critical systems, the lack of embedded countermeasures exposes them to exploitation.”
Indeed, the Department of Commerce on May 15 took another swipe at Chinese telecoms behemoth Huawei and tightened its earlier efforts to block it from exporting its semiconductors and products to the US and allies. The Trump administration alleges that Huawei's hardware and software, in particular that related to 5G wireless technology, are full of deliberate security holes in order to enable Chinese government spying. The ruling by Commerce's Bureau of Industry and Security, which will take effect in September, seeks to prevent companies around the world from using American-made software and machinery develop chips for Huawei or its subsidiary firms.
The problem for device-makers, particularly in the IoT world where the market is largely for commercial products (think smart refrigerators), is that fixing potential security holes often isn't seen as worth the time, effort and most importantly, money.
“The inclusion of security also often requires certain trade-offs with the typical design objectives, such as size, performance, and power dissipation,” the DARPA spokesperson said. “For example, something like a sprinkler isn't likely to require the highest level of security protections. Investing in security mechanisms that take up a lot of space on the underlying chip, or significantly impact chip performance likely doesn't make sense based on the sprinkler's expected use and application.”
And yet, that future IoT sprinkler also will be other IoT devices and computer networks in operation by an individual, a company or a facility, such as a weapons depot.
Even more unfortunately, the spokesperson explained, “modern chip design methods are unforgiving – once a chip is designed, adding security after the fact or making changes to address newly discovered threats is nearly impossible.”
Thus, the AISS program is aimed at spurring research into two areas that can address four types of microchip vulnerability, the release says: “side channel attacks, hardware Trojans, reverse engineering, and supply chain attacks, such as counterfeiting, recycling, re-marking, cloning, and over-production.”
The first area of research will be focusing on “development of a ‘security engine' that combines the latest academic research and commercial technology into an upgradable platform that can be used to defend chips against attacks, and provide an infrastructure to manage these hardened chips as they progress through their lifecycle,” DARPA said.
The second area, led by software specialists Synopsys, “involves integrating the security engine technology developed in the first research area into system-on-chip (SOC) platforms in a highly automated way,” the DARPA release said. The Synopsys team also will be working on how to integrate new security designs and manufacturing tools with currently available off-the-shelf products.
Nicholas Paraskevopoulous, sector VP for emerging capabilities development at Northrop Grumman, said in a May 27 press release that the firm's “design tools will enable the development of secure and trusted integrated circuits with reduced costs.” Northrop Grumman is involved in the first AISS research area.

Feb. 19 (UPI) -- Sikorsky Aircraft was awarded a $470.8 million modification for six VH-92A helicopters for the presidential helicopter replacement program. The deal modifies a $542 million contract awarded in June to build six new helicopters for the Presidential fleet. Under the modification, Sikorsky -- a division of Lockheed Martin -- will provide interim contractor support and six cabin interior reconfiguration kits as well as six low rate initial production lot II VH-92A aircraft for the presidential fleet. The Navy plans to replace the current Marine Corps fleet of 19 helicopters, composed of the VH-3D, which entered service in 1978 and the VH-60N aircraft, which arrived in 1987 -- with 23 new aircraft. The VH-92A is designed to increase performance and payload, including crew coordination systems and communications capabilities, and be easier to maintain. In December, General Electric received an $11.1 million contract to build five CT7-8A6 engines for the presidential helicopter fleet. https://www.upi.com/Defense-News/2020/02/19/Sikorsky-lands-4708M-deal-for-presidential-helicopter-upgrade/1301582159979/

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
