中文摘要：

基于无证书短签名,提出一种资源受限环境下的无证书聚合签名方案,由指定的聚合者发起签名协议,引入包含随机数的状态信息,使得每一轮聚合签名产生不同的状态信息。实验结果表明,与传统的无证书聚合签名方案相比,该方案能在可证安全的基础上降低计算开销,并且在随机预言模型下是存在性不可伪造的。

英文摘要：

On the basis of the certificateless short signature, this paper proposes a certificateless aggregate signature scheme in resource constrained environment. A signature protocol is initiated by the specified aggregator. The state information including random numbers is introduced to make each round of aggregated signature generate different state information. Experimental results show that, compared with the traditional certificateless aggregate signature scheme, the proposed scheme can reduce computation overhead on the basis of provable security, and can be falsified under random oracle model.
