一种强前向安全的数字签名方案
A Strong Forward-secure Digital Signature Scheme
摘要
Abstract
Aiming at the problem of key disclose in existed digital signature schemes, a strong forward secure signature scheme, which is based on Guillou-Quisquater signature and Rabin cryptosystem is proposed. In this new scheme, the signer can produce one signature key by the traditional forward technology, and then generate another key with reverse thinking. The use of the two keys makes attackers can not forge the signer’s previous and subsequent periods of valid signatures even if they get the signer’s keys of the current period. Analysis result shows that it is correct and secure, moreover, it has the property of strong forward security. It is also less time-consuming than existing shcemes.关键词
