Group key agreement (GKA) allows a set of players to establish a shared secret and thus bootstrap secure group communication. GKA is very useful in many types of peer group scenar...
At Indocrypt 2005, Viet et al., [22] have proposed an anonymous password-authenticated key exchange (PAKE) protocol and its threshold construction both of which are designed for cl...
The standard solution for user authentication on the Web is to establish a TLS-based secure channel in server authenticated mode and run a protocol on top of TLS where the user en...

Abstract. Multiparty signature protocols need protection against roguekey attacks, made possible whenever an adversary can choose its public key(s) arbitrarily. For many schemes, p...
We present the first cryptographically sound security proof of the well-known Otway-Rees protocol. More precisely, we show that the protocol is secure against arbitrary active att...
