摘　　要：数字签名是一种身份认证技术,它在实现身份认证、数据完整性、不可抵赖性功能等方面都有着重要的应用。基于CPK组合公钥原理和椭圆曲线数字签名原理,提出了一种新的组合密钥生成映射算法和数字签名方案。新算法和方案提高了组合密钥和数字签名的生成速度,节约系统资源,具有一定的理论和应用价值。Digital signature is an identity authentication technology,which in the realization of identity authentication,data integrity,non-repudiation function have important applications.Based on the theory of CPK and elliptic curve public key digital signature,this paper presents a new algorithm of combination key and a digital signature scheme.New algorithms and programs could improve the speed of combination key and also generation of digital signature.The algorithms and programs also could save system resources and have some theoretical and practical value.
