An enhanced certificateless authenticated key agreement protocol

Authenticated key agreement protocol is used to share a secret key for encrypting data being transferred between two or more parties over a public network. An implementation of this protocol is the certificateless key agreement which utilizes the features of the identity-based public key cryptography and the traditional public key infrastructure. This implementation can produce multiple public keys for a corresponding private key. In this paper, an alternative key generation technique is proposed for certificateless public key cryptography in order to have one public key for one private key. This will improve the security features of the relevant key generation. Furthermore, the efficiency of the proposed protocol is presented in terms of computational operation. The comparison analysis shows that the proposed protocol conveys better efficiency with all the known security attributes compared to the existing protocols.
