摘要: 在高铁路轨信号检测系统中,各检测终端和传感器收集信号的传输安全性和可靠性至关重要,但相关信号处理设备计算能力受限且实时性要求较高。为此,提出一种新的无证书聚合签名方案,并设计敌手模型。在随机预言机模型下,证明了方案对自适应选择消息和假定敌手攻击是存在性不可伪造的,由于未使用双线性映射运算,相比基于身份的聚合签名和固定长度的无证书聚合签名方案计算效率有所提高且易于实现,适用于带宽较低、存储和计算受限的高铁路轨检测网络信号安全传输过程的数据认证服务。

Abstract: The security and reliability of the transmission of signals collected by the detection terminals and sensors of great importance in the high-rail track signal detection system.However,the relevant signal processing device is limited in computing power and it needs higher real-time requirements.Therefore a certificateless aggregate scheme and a new adversary model are proposed.Under the random oracle model,it is proved that the scheme cannot be provably forged by the adaptive chosen-message and adversary assumption attack.Moreover,compared with other existing aggregate signature schemes like identity-based aggregate signature or certificateless aggregate signature with constant length in the computational efficiency,the proposed scheme is more efficient as it doesn’t contain bilinear pairings.And this scheme is more suitable for the application in secure signal transmission and data authentication service of the high-rail track detection network system which has low bandwidth as well as limited storage and computing environment.

Key words: aggregate signature, Discrete Logarithm Problem(DLP), linear mapping, random oracle model, signal detection
