摘要 无证书公钥密码体制是在基于身份的公钥密码体制的基础上提出的新型公钥密码体制,它避免了密钥托管问题,也不需要使用公钥证书。代理重加密可以针对同一明文,实现不同用户公钥加密的密文之间的转换,在这个过程中半可信的代理者不能获得关于消息M的任何信息。文中将无证书公钥密码体制和代理重加密结合起来,介绍了一个基于双线性对的无证书代理重加密方案,该方案在标准模型下是抗适应性选择消息攻击的。 Certificateless public key cryptography is a new type of public key cryptography which is developed from identity based cryptography. It can avoid the key escrow problem and do not need public key certificate either. Proxy re-encryption allows the proxy to transform a ciphertext under Alice＇ s public key into a new ciphertext under Bob＇ s public key on the same message, while the proxy can＇ t obtain any underlying plaintext. This paper combined the certificateless public key cryptography and proxy re- encryption together and proposed a certificateless proxy re-encryption scheme from pairing, which has chosen ciphertext security in standard model.
