摘要: 基于前向安全数字签名和代理签名,利用双线性对构造一个新的前向安全的代理签名方案。在该方案中,即使某一时刻代理签名者的密钥泄露,以前时段产生的代理签名仍有效。新方案不仅满足代理签名的可验证性、不可伪造性、不可抵赖性等性质,还满足前向安全性。

Abstract: Based on the theory of forward-secure digital signature and proxy signature scheme, a new forward-secure proxy signature scheme is proposed under the use of bilinear pairings. This scheme is to preserve the validity of past proxy signature even if the current secret key of proxy signer has been compromised. It not only has the properties of proxy signature, such as verifiability, unforgeability, undeniability, but also has the properties of forward security.

Key words: forward-secure, bilinear pairings, proxy signature
