摘　　要：基于无证书密码体制,提出了一种可验证的环签密方案模型,并给出了基于双线性对的具体方案。该方案能够使消息发送者以匿名的方式发送消息,并可同时实现保密性和认证性两种功能。此外,在需要证实签密人身份时,能够公开验证其身份。在随机预言模型下证明了该方案可以抵抗自适应选择密文攻击。A new model named verifiable certificateless ring slgncryption scheme was presented. A scheme based on bilinear pairings was also given. Using the scheme, the message sender can anonymously send the message, and the confidentiality and authenticity of the message are realized at the same time. If necessary, the real signer can prove his identity. Thus the scheme has been proved to be secure in the random oracle model.
