We give the first proof of security for the full Unix password hashing algorithm (rather than of a simplified variant). Our results show that it is very good at extracting almost...

Traditional password-based authentication and key-exchange protocols suffer from the simple fact that a single server stores the sensitive user password. In practice, when such a ...

We mathematically explore a model for the shortness and security for passwords that are stored in hashed form. The model is implicitly in the NIST publication [8] and is based on c...

We define a new notion of relatively-sound non-interactive zeroknowledge (NIZK) proofs, where a private verifier with access to a trapdoor continues to be sound even when the Ad...

This paper presents a secure constant-round password-based group key exchange protocol in the common reference string model. Our protocol is based on the group key exchange protoco...
