Abstract:
This paper proposes a forward security proxy multi-signature scheme on the basis of the forward-security idea and proxy multi-signature schemes. The new scheme satisfies security properties of general proxy multi-signature schemes and has forward-security. Under the strong RSA assumption, Diffie-Hellman problem and discrete logarithm problem over finite field, the new scheme has good forward security.
Key words:
proxy multi-signature,
forward security,
strong RSA assumption,
Diffie-Hellman problem
摘要:
将前向安全的思想与代理多重数字签名结合,提出一个前向安全的代理多重签名方案,该方案不仅满足一般代理多重签名方案的性质,而且具有前向安全性。在强RSA假定、计算式Diffie-Hellman问题及有限域上离散对数问题难解的假设下,该方案具有良好的安全性。
