Modeling Key Compromise Impersonation Attacks on Group Key Exchange Protocols
A key exchange protocol allows a set of parties to agree upon a secret session key over a public network. Two-party key exchange (2PKE) protocols have been rigorously analyzed unde...

Universally composable contributory group key exchange
We treat the security of group key exchange (GKE) in the universal composability (UC) framework. Analyzing GKE protocols in the UC framework naturally addresses attacks by maliciou...
