Identity Based Authenticated Group Key Agreement Protocol
An important and popular trend in modern computing is to convert traditional centralized services into distributed services spread across multiple systems and networks. One-way function trees can be used to extend two-party Key Agreement protocols to n-party protocols. Tree-based Group Diffie-Hellman [17] is one such protocol. This paper proposes the first Identity based Group Key Agreement pro...
متن کاملEfficient Identity-Based and Authenticated Key Agreement Protocol
Several identity based and authenticated key agreement protocols have been proposed in recent years and all of them have been shown to be non-secure. It remains an open question to design secure identity based and authenticated key agreement protocols. In this paper, we propose an efficient identity-based and authenticated key agreement protocol IDAK using Weil/Tate pairing. A security model fo...
متن کاملIdentity-Based Authenticated Asymmetric Group Key Agreement Protocol
In identity-based public-key cryptography, an entity’s public key can be easily derived from its identity. The direct derivation of public keys in identity-based public-key cryptography eliminates the need for certificates and solves certain public key management problems in traditional public-key cryptosystems. Recently, the notion of asymmetric group key agreement was introduced, in which the...
متن کاملAn Extended Identity Based Authenticated Asymmetric Group Key Agreement Protocol
Lei et al. [26] proposed a new asymmetric group key agreement protocol allowing a set of users to negotiate a common encryption key accessible by any user, and each user holds her respective decryption key. This enables the confidential message communication among group users, and grants any outsider to send message to the group. In this paper, an authenticated asymmetric group key agreement pr...
متن کاملIdentity Based Authenticated Key Agreement from Pairings
We present a new identity based authenticated key agreement protocol from pairings satisfying the required security attributes. The security of our protocol is based on the bilinear Diffie-Hellman assumption.
