A Pairing-free ID-based Key Agreement Protocol with Different PKGsMay 19th, 2015
This paper proposes an identity based key agreement pro- tocol based on elliptic curve cryptography (ECC) between users of different networks with independent private key generations (PKGs). Instead of bilinear pairings which commonly used for contracting identity based schemes, the proposed protocol makes use of elliptic curves to ob- tain more computational efficiency. The proposed proto- col develops Cao et al’s protocol for situations that two users of independent organizations or networks with sep- arate servers (that in this article, are named PKGs, based on their main duty, generating private keys for the users) want to share a secret key via an insecure link. The main novelty of this paper is security proof of the proposed protocol in the random oracle model. The security proof argues the security attributes of the proposed protocol.
