Protecting data integrity and achieving non-repudiation in wireless sensor networks (WSNs) is very essential during data communication from one sensor to another. However, wireless sensor network nodes are severely limited by power, communication bandwidth, and storage space, so the traditional signature algorithm cannot be adapted to the environment. In this paper, we have proposed a certificateless aggregate signature scheme (CL-ASS) for WSNs. This scheme not only can significantly reduce the bandwidth consumed by network transmission and the occupancy of node storage space but also provides high privacy. In the random oracle model, we demonstrate the security of the scheme against two types of adversaries, under the assumption of the hardness of the computational Diffie–Hellman (CDH) Problem. Finally, the performance analysis shows that our scheme has an ideal computational and communication cost.

在无线传感器网络 (WSN) 中保护数据完整性和实现不可否认性在从一个传感器到另一个传感器的数据通信过程中非常重要。然而，无线传感器网络节点受到功率、通信带宽和存储空间的严重限制，因此传统的签名算法无法适应环境。在本文中，我们为 WSN 提出了一种无证书聚合签名方案（CL-ASS）。该方案不仅可以显着降低网络传输消耗的带宽和节点存储空间的占用，而且还提供了很高的隐私性。在随机预言机模型中，在计算 Diffie-Hellman (CDH) 问题的难度假设下，我们证明了该方案针对两类对手的安全性。最后，
