摘要 根据电子投票和电子抽奖的需要,提出了可验证可关联的环签名概念。利用密码哈希函数的良好性质和DLP的困难性问题,构造了一个可验证可关联的环签名方案。通过安全分析,该方案满足存在不可伪造性、签名者匿名性、可关联性、可验证性等特点。 Based on the need of E-voting and E-lottery,the notion of verifiable and linkable ring signature is put forward. Making use of the good properties of cryptography Hash functions and the difficulties of DLP,a verifiable and linkable ring signature scheme is constructed.Through the security analysis,the scheme satisfies the following properties:Existential unforgeable, signer ambiguous,linkable and verifiable.
