A block-free TGDH key agreement protocol for secure group communications
نویسندگان
چکیده
Secure group communication (SGC) has been an active research area because several applications require it. In this paper, we propose a Block-Free Group Tree-based Diffie-Hellman (BF-TGDH) key agreement protocol, based on a recently proposed Group Treebased Diffie-Hellman (TGDH) key agreement protocol, for secure group communication. The new protocol has the following specific properties: (1) no blocking during the rekeying process and seamless group communication without any interruption; (2) resistance to the Man-inthe-Middle attack; (3) authentication of message senders using inherent (ElGamal) signature protocol.

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 ...
