摘　　要：随着工业物联网的发展,数据拥有方需要对大量的数据进行处理,同时,对数据的收集和传送效率提出更高的要求。在工业物联网系统中,数据拥有方领导为了减少工作量,可以通过授权部门主管对数据进行相关处理。密码学中,代理聚合签名可以安全可靠的实现权利的委托授权,同时通过签名的聚合后,减少了数据的存储空间,提高数据的传输效率和验证效率。因此,设计一个高效的代理聚合签名方案是有必要的。首先,提出了一个适用于工业物联网的高效安全的基于证书的代理聚合签名方案。其次,在随机预言模型下,基于椭圆曲线上离散对数困难问题,给出了安全性证明。最后,通过与其他代理聚合签名方案计算效率和安全性的比较,结果表明新方案的计算效率更高。With the development of the industrial internet of things(IOT),data owners need to process large amounts of data,and at the same time,put higher demands on the efficiency of data collection and transmission.In the industrial IOT system,the data owner's leader can authorize department heads to handle relevant data processing tasks in order to reduce workload.In cryptography,proxy aggregation signatures can securely and reliably achieve delegation of authority.By aggregating signatures,data storage space is reduced,and data transmission and verification efficiency is improved.Therefore,it is necessary to design an efficient proxy aggregation signature scheme.Firstly,an efficient and secure certificate-based proxy aggregation signature scheme for the Industrial Internet of Things is proposed.Secondly,under the random oracle model,based on the discrete logarithm problem on the elliptic curve,a security proof is presented.Finally,by comparing the computational efficiency and security of the new scheme with other proxy aggregation signature schemes,the results indicate that the new scheme has higher computational efficiency.
