Certificate-based proxy aggregation signature scheme suitable for industrial internet of things
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 stor-age space is reduced,and data transmission and verification efficiency is improved.Therefore,it is nec-essary to design an efficient proxy aggregation signature scheme.Firstly,an efficient and secure certifi-cate-based proxy aggregation signature scheme for the Industrial Internet of Things is proposed.Second-ly,under the random oracle model,based on the discrete logarithm problem on the elliptic curve,a se-curity 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.
