Provably secure threshold password-authenticated key exchange
2006
Journal of computer and system sciences (Print)
We present two protocols for threshold password authenticated key exchange. In this model for password authentication, the password is not stored in a single authenticating server but rather shared among a set of n servers so that an adversary can learn the password only by breaking into t + 1 of them. The protocols require n > 3t servers to work. The goal is to protect the password against hackers attacks that can break into the authenticating server and steal password information. All known
