With the ideas of designated - verifier signature scheme and proxy signature scheme , a new identity - based strong designated - verifier proxy signature scheme from bilinear pairings is proposed . the signature length of our scheme is shorter than wang ' s scheme [ 4 ] 基于指定验证者签名和代理签名的思想,提出了一个运用双线性对的基于身份的强指定验证者代理签名方案,该方案比文献[ 4 ]中的指定验证者代理签名方案的签名长度更短。
Hidden authentication conditional oblivious transfer based on oblivious attribute credentials ( oacerts ) and hidden credentials is proposed and a scheme based on bilinear pairing for implementing the idea is constructed which solves the problem that oacerts may exposure acme sensitive information of the receiver 摘要在不经意属性证书和隐藏证书的基础上提出了隐藏认证的有条件不经意传输，利用双线性对构造了一个具体方案，解决了不经意属性证书可能暴露接收者的某些敏感信息的问题。
