摘要
为加强变电设备信息交互的安全性,设计一种由数据采集装置和云服务中心组成的数据采集系统,提出一个可证明安全的聚合签名方案,在随机预言机模型和CDH困难问题下证明了方案的安全性。以此方案为基础设计一种适用于变电终端的数据传输协议,给出仿真代码实现,结果表明,方案计算量小、耗时较短、效率较高。与喻琇瑛等方案和罗敏等方案相比,该方案平均耗时分别减少约29.4%、19.6%,验证了其优越性和可行性,为有效解决多个变电终端数据安全传输提供了可参考方案。
To enhance the security of information interaction between substation equipments,a data acquisition system composed of data acquisition devices and cloud service center was designed,aprovable security aggregate signature scheme was proposed,and the security of the scheme was proved under the random oracle model and the CDH difficult problem.A data transmission protocol for substation terminal was designed on the basis of this scheme,and the simulation code was implemented.The results show that the scheme has smaller computation,shorter time-consuming,and higher efficiency.Compared with the scheme of Yuxiuying et al and Luomin et al,the average time-consumption of the proposed scheme is reduced by approximately 29.4% and 19.6% of that of their schemes respectively,which verifies that the proposed scheme is superior and feasible,and it provides a reference solution for effectively solving the data transmission of multiple substation terminals.
