Abstract. An authenticated group key exchange (AGKE) scheme allows a group of users in a public network to share a session key which may later be used to achieve desirable cryptogr...
In wireless ad hoc networks environment, Bellovin and Merritt first developed a password-based Encrypted Key Exchange (EKE) protocol against offline dictionary attacks using both ...
We consider the fundamental problem of authenticated group key exchange among n parties within a larger and insecure public network. A number of solutions to this problem have bee...
Cryptographic protocol design in a two-party setting has often ignored the possibility of simultaneous message transmission by each of the two parties (i.e., using a duplex channe...
In this paper, we present a new ID-based two-party authenticated key exchange (AKE) protocol, which makes use of a new technique called twin Diffie-Hellman problem proposed by Cas...
