摘要
自从1985年Neal.Koblitz和Victor.Miller首先提出了椭圆曲线密码以来,椭圆曲线理论越来越被人们重视.利用椭圆曲线密码体制的ECDH协议产生会话密钥,在会话密钥产生过程中,利用ECES-ElGamal协议对用于产生会话密钥的数据进行加密,同时利用ECDSA协议进行数字签名,这样可提高密钥的安全性并可确认双方的身份.利用该方法设计的会话密钥产生方案,只需要认证中心支持,而无需密钥分配中心管理,解决了密码体制中会话密钥存储与管理的问题.
Since the introduction of Elliptic Curve Cryptography by Neal.Koblit zand Victor.Miller in 1985, the theory of Elliptic Curve has been attached more and more importance to. In this paper, the meet-key is generated by using Elliptic Cure Key Agreement Scheme—Diffie-hellman .The data which generate meet-key are encrypted by using Elliptic Cure Encrypt Sheme—ElGamal and digital signature is processed by using Elliptic Cure Signature Scheme—Digital Signature Algorithm version, so as to improve the security of key and verify the identity.This meet- key generation scheme based on Capacity Authorization has no need to be managed by key distributed center. The problem about storage and management of meet-key has been solved by using the scheme.
