  US Spies Want to Know How to Spot Compromised AI

  BY DAVE GERSHGORN What if you were training an AI, and an adversary slipped a few altered images into its study set? The US government's research arm for intelligence organizations, IARPA, is looking for ideas on how to detect “Trojan” attacks on artificial intelligence, according to government procurement documents. Here's the problem the agency wants to solve: At a simple level, modern image-recognition AI learns from analyzing many images of an object. If you want to train an algorithm to detect pictures of a road signs, you have to supply it with pictures of different signs from all different angles. The algorithm learns the relationships between the pixels of the images, and how the structures and patterns of stop signs differ from those of speed-limit signs. But suppose that, during the AI-training phase, an adversary slipped a few extra images (Trojan horses) into your speed-limit-sign detector, ones showing stop signs with sticky notes on them. Now, if the adversary wants to trick your AI in the real world into thinking a stop sign is a speed-limit sign, it just has to put a sticky note on it. Imagine this in the world of autonomous cars; it could be a nightmare scenario. The kinds of tools that IARPA (Intelligence Advanced Research Projects Activity) wants would be able to detect issues or anomalies after the algorithm has been trained to recognize different objects in images. This isn't the only kind of attack on AI that's possible. Security researchers have also warned about inherent flaws in the way artificial intelligence perceives the world, making it possible to alter physical objects like stop signs to make AI algorithms miscategorize them without ever messing with how it was trained, called “adversarial examples.” While neither Trojan attacks nor the adversarial examples are known to have been used by malicious parties in the real world, researchers have said they're increasingly possible. IARPA is looking at a short timeline as well, expecting the program to conclude after a maximum of two years. https://www.defenseone.com/technology/2018/12/us-spies-want-know-how-spot-compromised-ai/153826

  The European Union’s defense ambitions are still showing signs of life

  By: Sebastian Sprenger COLOGNE, Germany — A new budget proposal for the European Union shows that the bloc's defense plans are back on the table as the continent pushes to revive its economy following the coronavirus crisis. Two flagship programs to that end — the European Defence Fund and the Military Mobility initiative — are set to receive €8 billion (U.S. $9 billion) and €1.5 billion (U.S. $1.7 billion), respectively, in the seven-year plan beginning in 2021, according to a proposal unveiled this week by European Commission President Ursula von der Leyen. Those figures are lower than the initial proposal of €13 billion and €6.5 billion for the two budget lines. But they represent an uptick compared with recent negotiation positions that envisioned defense-related spending slashed even more. Defense spending remains an unbeloved subject in many European countries, and it is notable that there is no dedicated political narrative around building military prowess in the context of the bloc's recovery plan, dubbed Next Generation EU during a May 27 speech by von der Leyen. Still, the fact that the European Defence Fund — designed to foster intra-continental defense cooperation — remains in the mix is in itself a statement, according to analysts. Defense-spending advocates in Europe believe a robust military can strengthen the EU's hand in trying to assert its role on the world stage with other players like China and Russia. The new proposal of €8 billion for the European Defence Fund may not seem like much, given the high, upfront costs for multinational military equipment projects, said Sophia Besch, a senior research fellow at the Center for European Reform. “But it's a win for the [European] Commission in the current political context,” she added. “COVID-19 has shifted the priorities, and even before the crisis there were signs that defense was losing ground in the traditional budget battles,” Besch said. Given that, the new proposal is “better than nothing,” she argued. At the same time, the de facto reduction would make it harder to prove for the commission that the intended effects can be achieved with the amount envisioned, Besch predicted. Funding through the European Defence Fund and its associated channels ensures that certain projects in many member states can happen at all, said Yvonni-Stefania Efstathiou, an Athens, Greece-based defense analyst specializing in the emerging European defense-cooperation framework PESCO, or Permanent Structured Cooperation. “Allocations to the EDF have the potential of triggering more defense cooperation, as those funds will be used to finance collaborative research and common capability development projects,” she said. What is still missing, however, is an overarching context of where the EU wants to go with its defense ambitions, she argued. “The impact of these funds will be limited unless there is also progress on the common definition of strategic priorities and military requirements.” The cut to the budget line for military mobility means member states stand to pay more of their own money for updating bridges, roads and rail networks to ensure military equipment can quickly move along the continent in the event of a standoff with Russia. The work is seen as a critical interface between the EU and NATO, and alliance officials previously expressed hope for a funding injection that could speed projects along, especially in Eastern Europe. “Unless we have the full costings of how much bridges and roads will cost, it is hard to evaluate whether the funds are sufficient,” Efstathiou said. “What is easy to predict, however, is the dissatisfaction of the Eastern European states.” https://www.defensenews.com/global/europe/2020/05/29/the-european-unions-defense-ambitions-are-still-showing-signs-of-life/
