| 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。 |
| 关 键 词： | 代理多重签名 前向安全 强RSA假定 Diffie-Hellman问题 |

| 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. |
| Keywords: | proxy multi-signature forward security strong RSA assumption Diffie-Hellman problem |
