有效的无证书签名方案

为解决基于身份的密码体制的密钥托管问题以及传统公钥密码体制的公钥认证问题，通过修改Barreto等人提出的高效的基于身份的签名方案中的私钥和公钥的产生算法，提出了一个无证书签名方案。该方案在随机预言模型下是可证明安全的，而且也是高效的方案，只需要一个对运算。

Efficient certificateless signature scheme

To solve the key escrow problem of ID based cryptography and the public key authentication of traditional public key cryptosystem, a certificateless signature scheme revising the private and public generation algorithms in Barreto et al.'s efficient ID based signature was proposed. The scheme is provably secure in the random oracle model, and is an efficient scheme. It only needs one pairing operation.
