Title:

Password-based Authenticated Key Exchange

Abstract:

Password-based protocols for authenticated key exchange are designed to work despite the use of passwords drawn from a space so small that an adversary might well enumerate, off line, all possible passwords. While several such protocols were suggested a long time ago, the underlying theory has only been developed for a few years. Efficient and secure protocols are thus now available for the two-party case. In this talk, we will see a brief history of these schemes, the security problems and the solutions. Even if such efficient and secure schemes exist, their practical application is not so simple. We will then present some possible variations to concrete applications.
