| 摘 要： | 结合基于身份的无可信中心签名机制和代理盲签名的特点，利用双线性对，提出一种无呵信私钥生成中心的代理盲签名方案．在方案中，密钥生成中心（PKG）是不参与用户的密钥生成，避免了用户密钥的泄露，解决了以往方案中密钥部分或者完全依赖PKG生成的问题．分析表明，该方案不仅满足代理盲签名所要求的各种性质，而且方案中PKG与用户间不再需要安全信道传送代理密钥．

| Abstract: | A new blind signature scheme without a private key generator party is presented, which satisfies the security of both proxy blind signature scheme and without trusted private key generator by using bilinear pairings. In the scheme, the Private Key Generator （PKG） is not involved in the user＇s key generation, and the problems that the past scheme partially or completely depends on the PKG to generate the private key are solved. Analysis shows that the proposed scheme can satisfy all the required properties of a proxy blind signature , and it does not need the security channel between PKG and users. |
