基于ECDSA的三方口令认证密钥交换协议
ECDSA-based Password Authenticated Key Exchange Protocol for Three-party
摘要
Abstract
In order to against dictionary attack and server compromise attack, this paper proposes a Elliptic Curve Digital Signature Algorithm(ECDSA)-based password authenticated key exchange protocol for three-party. ECDSA is divided into public key generation, signature verification process and verification process. On the bases of it, this protocol is divided into six steps, and designs mutual authentication mechanism. And any two clients can accomplish key exchange relying on the server. Analysis results show that this protocol can reduce the calculation difficulty and storage cost, and can resist dictionary attacks and server compromise attack.关键词
