【摘要】 提出了一种指定接收者椭圆曲线门限群签名加密方案.该方案根据Nyberg和Rueppel方法,利用椭圆曲线加密技术将门限群签名与指定接收者公钥加密有机地结合在一起,构造一种指定接收者的门限签名群加密方案.与传统的消息加密再数字签名的方法相比,该方案具有数据传输安全、计算复杂度和通讯复杂度低、通讯带宽小等优点.更多还原

【Abstract】 An elliptic curve threshold signature encryption scheme with the specified verifier is proposed.Being based on the method of Nyberg-Rueppel,The scheme uses the elliptic curve threshold to integrate threshold signature scheme with public key cryptosystem to construct a thresh-old signature encryption scheme with the specified verifier.Compared with common scheme which signatures data after encrypting it,this scheme has more secure data transmission,less complicate degree in calculate and communication,and less communication bandwidth.更多还原
