一个可证明安全的签名方案

A Provably Secure Signature Scheme

可证明安全是指方案的安全性可以被证明,即该方案能够抵抗密码攻击。随机预言模型是可证明安全中的重要工具。近年来,椭圆曲线密码由于具有良好的性质,而引起了人们的普遍关注。利用椭圆曲线上的双线性对,设计一个签名方案,该方案在随机预言模型下是可证明安全的,并且效率也很高。

Provable security means the scheme can be proven secure and it can withstand cryptanalytic attacks. Random oracle model has been an important tool in the theory of provable security. Recently, as elliptic curve cryptography has better characters, it attracts the people. Proposes an efficient signature scheme based on bilinear pairings, and it can be proven to be secure in the random oracle model.
