摘 要: 指出了文献提出的前向安全聚合签名方案不具有前向安全性,并提出了一个基于双线性对构造的具有前向安全性的聚合签名方案。该方案具有防止因签名密钥泄露而带来的签名失效的性质,同时由于其签名的聚合性质,可以将多个签名聚合成单个签名,从而大大提高数据的传输和存储效率。最后,分析了方案的正确性和安全性。

Abstract: This paper pointed out that the forward secure aggregate signature scheme proposed in reference actually did not have the property of forward security. Furthermore, a new aggregate signature scheme based on bilinear maps with forward security was proposed. This scheme can prevent signature invalid resulting from leakage of sinning key. In addition, due to the aggregatability, it enables multiple signatures to aggregate into one signature, which improve the efficiency of data storage and transition significantly. Finally, analysis for consistency and security of this scheme was also provided.
