Multiauthority Traceable Ring Signature Scheme for Smart Grid Based on Blockchain

As the next-generation power grid system, smart can realize balance of supply and demand help in communication security privacy protection. However, real-time consumption data collection might expose users’ information, such as their living habits economic conditions. In addition, during process transmission, it may lead to inconsistency between user side storage side. Blockchain provides tamper-resistant traceable characteristics for solving these problems, ring signature schemes provide an anonymous authentication mechanism. Therefore, this work, we consider applications scheme based on blockchain. We introduce notion multi-authority (MA-TRS) distributed setting. our scheme, there is auditing node that distinguish identity real signer from without any secret information. Last but not least, prove proposed unforgeable, anonymous, traceable.
