摘　　要：针对Di Ma等人提出的前向安全的顺序聚集签名方案,提出了一个新的改进方案。该方案使每个时段能够对多个消息产生多个签名,同时把签名聚集算法分成两个独立的算法——签名生成算法和聚集算法。新的方案能够满足实时性和并发性要求,还能够满足一些特殊无线传感器网络的需求。In this paper,Di Ma,who firstly advanced by Di Ma called forward secure sequential aggregate （FssAgg）signature,we proposed a modified schemederived from FssAgg signature scheme and called it as forward—— secure aggregation of signatures. This newly scheme separates the sign-and-aggregate algorithminto two dependent algorithms and signs messages noboundary per time period. It can be useful in some scenario in wireless sensor network.supplying real-time and better concurrency.
