摘要：Recently, many identity-based two-party authenticated key agreement (ID-2PAKA) protocols using elliptic curve cryptography (ECC) have been proposed, however, these protocols do not provide adequate security and their computation costs are also relatively high due to bilinear pairing and map-to-point function. Moreover, they require many communication rounds for establishing the session key, and thus results in increased communication latency, which makes them unsuitable for real applications. This paper thus aims to propose a pairing-free ID-2PAKA protocol based on ECC that removes the security flaws of previous protocols. The proposed protocol helps two users to establish a common session key between them through an open network. The formal security analysis using BAN logic and the comparisons with other protocols are given, which demonstrated that our protocol is formally secure and thus, suitable for secure and efficient peer-to-peer communications.
