A group key agreement protocol (GKA) allows a set of players to establish a shared secret key which can be used to secure a subsequent communication. Several efficient constantrou...
Abstract. We introduce a new approach for cryptanalysis of key agreement protocols based on noncommutative groups. Our approach uses functions that estimate the distance of a group...
Secure and reliable group communication is an increasingly active research area by growing popularity in group-oriented and collaborative application. One of the important challeng...

The Diffie-Hellman key agreement protocol is based on taking large powers of a generator of a prime-order cyclic group. Some generators allow faster exponentiation. We show that to...
