Then,we provide some theoretical discussions for the security model for MVESSs,and show that our new scheme can be proven to secure with the hardness assumption of the computational Diffie-Hellman problem of pairings in the random oracle model.

• 随后；本文讨论了混合可验证加密签名体制的安全模型；并在随机谕示模型下；基于双线性映射的计算性D iffie-Hellman问题难解性假设；证明本文体制是可证安全的.
