Key agreement protocols are designed to establish a session keys between two or multiple entities oven an insecure network and the session key is used to assure confidentiality thought encryption. With the advantages of identity-based (ID-based) cryptography, there have been many ID-based key agreement protocols proposed. However, most of them are based on Weil pairing, which is more cost of computation compared with Tate paring. In this paper, we propose a newly ID-based key agreement protocol from the Tate pairing. Compared with previous protocols, the new protocol minimizes the cost of computation with no extra message exchange time. In addition, the proposed protocol provides known key security, no key control, no key-compromise impersonation and perfect forward secrecy.
