Cryptography Guru Martin Hellman Urges International Cooperation on AI, Security

Martin Hellman "achieved legendary status as co-inventor of the Diffie-Hellman public key exchange algorithm, a breakthrough in software and computer cryptography," notes a new interview in InfoWorld. Nine years after winning the Turing award, the 78-year-old cryptologist shared his perspective on some other issues: What do you think about the state of digital spying today? Hellman: There's a need for greater international cooperation. How can we have true cyber security when nations are planning - and implementing - cyber attacks on one another? How can we ensure that AI is used only for good when nations are building it into their weapons systems? Then, there's the grandaddy of all technological threats, nuclear weapons. If we keep fighting wars, it's only a matter of time before one blows up. The highly unacceptable level of nuclear risk highlights the need to look at the choices we make around critical decisions, including cyber security. We have to take into consideration all participants' needs for our strategies to be effective.... Your battle with the government to make private communication available to the general public in the digital age has the status of folklore. But, in your recent book (co-authored with your wife Dorothie [and freely available as a PDF]), you describe a meeting of minds with Admiral Bobby Ray Inman, former head of the NSA. Until I read your book, I saw the National Security Agency as bad and Diffie-Hellman as good, plain and simple. You describe how you came to see the NSA and its people as sincere actors rather than as a cynical cabal bent on repression. What changed your perspective? Hellman: This is a great, real-life example of how taking a holistic view in a conflict, instead of just a one-sided one, resolved an apparently intractable impasse. Those insights were part of a major change in my approach to life. As we say in our book, "Get curious, not furious." These ideas are effective not just in highly visible conflicts like ours with the NSA, but in every aspect of life. Hellman also had an interesting answer when asked if math, game theory, and software development teach any lessons applicable to issues like nuclear non-proliferation or national defense. "The main thing to learn is that the narrative we (and other nations) tell ourselves is overly simplified and tends to make us look good and our adversaries bad."
