A Smart Grid Privacy Protection Scheme Based on Short Fail-Stop Signature

In promoting the development of intelligent and distributed power transmission systems, smart grid has attracted extensive attention. However, the data transmitted over smart grids are not protected, and then suffer from several types of security threats and attacks. How to provide an efficient security protocol to enhance the privacy protection of smart grid network and prevent information leakage has become a hot research topic of smart grid privacy protection. In this paper, a short fail-stop signature scheme based on factorization and discrete logarithm assumption is designed to protect the information privacy of smart grid. The proposed scheme can not only protect the privacy of smart devices in the smart grid, but also prevent the forgery of payment credentials, and ensure the trusted center to effectively manage and maintain smart grid users and payment credentials.
