    An Efficient Certificateless Authenticated Key Agreement

    Key agreement is very important in information and data security. To overcome the key escrow property of identity-based cryptography and combines the advantages of the traditional PKI and the identity-based cryptography, certificateless public key cryptography is proposed. This paper proposed a new certificateless two-party key agreement protocol and gives the...
