摘要:
自从Bellare和Miner提出了前向安全数字签名方案的概念后,一些前向安全签名方案相继被提出。由于双线性配对函数表现出的良好密码学特性,目前已经引起了众多关注。本文在一个基于双线性配对函数的签名方案的基础上构造了一个前向安全签名方案。在计算Diffie-Hellman假设成立的情况下,此方案在随机预言模型中是不可伪造的前向安 安全签名方案。 [

Abstract:
After Bellare and Miner introduced a forward-secure digital signature scheme, some related schemes were proposed. Due to the various applications of t he bilinear pairings in cryptography, there have been many pairing-based signature schemes. In this paper, we describe a forward-secure signature scheme from a paring-based short signature scheme using bilinear pairings. It is an unforgeable forward secure scheme based on the computational Diffie-Hellma n Assumption in the random oracle model.
Key words: (forward-secure, digital signature, bilinear pairings)
