On the security of an identity-based authenticated group key agreement protocol for imbalanced mobile networks
passive attack forward secrecy backward secrecy
2013/2/21
Recently, Islam and Biswas proposed a pairing-free identity-based authenticated group key agreement protocol for imbalanced mobile networks. However, in this letter, we point out that this protocol ca...
Cryptanalysis of a pairing-free identity-based authenticated group key agreement protocol for imbalanced mobile networks
group key agreement imbalanced mobile networks
2013/2/21
Recently, Isalam and Biswas proposed a new group key agreement (GKA) protocol for imbalanced mobile networks. In this letter, we will show that Isalam et al.’s GKA protocol is not secure.

An Authenticated Group Key Agreement Protocol on Braid groups
braid groups conjugacy problem key agrement protocol
2009/4/8
In this paper, we extend the 2-party key exchange protocol on braid groups
to the group key agreement protocol based on the hardness of Ko-Lee problem. We also
provide authenticity to the group key ...
Rethinking the security of some authenticated group key agreement schemes
Rethinking authenticated group key agreement schemes
2009/4/3
In this paper we analyse three improved authenticated group key agreement
schemes, all of which are based on the conference key distribution systems
proposed by Burmester and Desmedt. We show that a...
