首先将基于门限结构的彼得森可验证秘密共享方案(Pedersen-VSS)转换成可以抵抗一般结构敌手攻击的方案(Pedersen-VSS-General).指出R. Canetti等人在设计分布式密钥生成方案(DL-Key-Gen)时,关于零知识证明使用的一个错误,并给出一种改进方案.基于以上设计,提出一个可以抵御一般结构敌手攻击的自适应安全的分布式密钥生成方案,该方案的安全性不依赖于“擦除”假设.对于这个方案给出详细的基于黑盒模拟的安全性证明. Firstly, Pedersen-VSS based on threshold structure is transformed into Pedersen-VSS-General, which can resist general structural adversarial attack.It is pointed out that R. Canetti et al in the design of distributed key generation scheme (DL-Key-Gen), an error about the use of zero-knowledge proof is given and an improved scheme is proposed.Based on the above design, an adaptive secure distributed key generation scheme that can resist general structural adversarial attacks is proposed, The security of this scheme does not depend on the “erase” hypothesis. For this scheme, a detailed proof of security based on black-box simulation is given.
