Security Analysis of an ID-Based Key Agreement for Peer Group Communication
نویسندگان
چکیده
Pairing based cryptography has been researched intensively due to its beneficial properties. In 2005, Wu et al. [3] proposed an identity-based key agreement for peer group communication from pairings. In this letter, we propose attacks on their scheme, by which the group fails to agree upon a common communication key. key words: group key agreement, cryptanalysis, pairings, impersonation attack.

Provably secure and efficient identity-based key agreement protocol for independent PKGs using ECC
Key agreement protocols are essential for secure communications in open and distributed environments. Recently, identity-based key agreement protocols have been increasingly researched because of the simplicity of public key management. The basic idea behind an identity-based cryptosystem is that a public key is the identity (an arbitrary string) of a user, and the corresponding private key is ...
متن کاملAnonymous ID-based Group Key Agreement Protocol without Pairing
Secure group communication is an active area of research and its popularity is fuelled by the growing importance of group-oriented applications such as teleconferences, collaborative workspace, pay per-view etc. A number of group key agreement protocols have been proposed for these objectives. However most of the protocols have not considers the anonymity of the participants. Although in some a...
متن کاملPerfect Forward Secure ID-based Key Agreement Protocol in Group Communication
Several identity-based key agreement protocols using bilinear pairing have been proposed in recent years and none of them has achieved all required security properties. In this paper, we firstly propose an ID-based one round authenticated group key agreement protocol with bilinear pairings, where all participants can generate the group session key in one round. Based on the intractability of el...

Group key agreement (GKA) protocols Play a main role in constructing secure multicast channels. These protocols are algorithms that describe how a group of parties communicating over a public network can gain a common secret key.
