Cris Moore, Professor, Santa Fe Institute April 13, 2011 Caesar shifted each letter three places in the alphabet. Much of modern computer science was born in the effort to break the Nazi Enigma code, and Cold War spies used code books that fit inside a walnut. Nowadays, the cryptography we depend on every day — for instance, to send our credit card information when we buy something on the Web — relies in turn on the mathematics of prime numbers. But in 1994, Peter Shor discovered that a future quantum computer could crack our cryptosystems by breaking large numbers into their prime factors. Cris will start by describing how these cryptosystems work, and how a quantum computer could break them. (Nothing beyond high-school math, he promises!) He'll end by giving a personal view about whether quantum computers can be built — and what kinds of cryptography could remain secure even if and when they are built.

Yael Tauman Kalai, Bhavana Kanukurthi, and Amit Sahai Microsoft Research; Boston University; and University of California (UCLA) Abstract. A large and growing body of research has sought to secure cryptographic systems against physical attacks. Motivated by a large variety of real-world physical attacks on memory, an important line of work was initiated by Akavia, Goldwasser, and Vaikuntanathan [AGV09] where security is sought under the assumptions that: (1) all memory is leaky, and (2) leakage can be an arbitrarily chosen (efficient) function of the memory. However, physical attacks on memory are not limited to leakage through side-channels, but can also include active tampering attacks through a variety of physical attacks, including heat and EM radiation. Nevertheless, protection against the analogous model for tampering — where (1) all memory is tamperable, and (2) where the tampering can be an arbitrarily chosen (efficient) function applied to the memory — has remained an elusive target, despite significant effort on tampering-related questions. In this work, we tackle this question by considering a model where we assume that both of these pairs of statements are true — that all memory is both leaky and (arbitrarily) tamperable. Furthermore, we assume that this leakage and tampering can happen repeatedly and continually (extending the model of [DHLW, BKKV10] in the context of leakage). We construct a signature scheme and an encryption scheme that are provably secure against such attacks, assuming that memory can be updated in a randomized fashion between episodes of tampering and leakage. In both schemes we rely on the linear assumption over bilinear groups. We also separately consider a model where only continual and repeated tampering (but only bounded leakage) is allowed, and we are able to obtain positive results assuming only that "self-destruct" is possible, without the need for memory updates. Our results also improve previous results in the continual leakage regime without tampering [DHLW, BKKV10]. Whereas previous schemes secure against continual leakage (of arbitrary bounded functions of the secret key), could tolerate only 1/2-ε leakage-rate between key updates under the linear assumption over bilinear groups, our schemes can tolerate 1-ε leakage-rate between key updates, under the same assumption.
