Asymmetric Encryption for Secure Stability Control of Cyber-Physical Power System

As an important part of the information physical system, smart grid not only greatly improves the collaborative ability and operation efficiency of the traditional power system, but also brings the increasing payment security problem. However, deposits for off-chain transactions would be threatened by counterparty collusion. Therefore, in order to solve this problem, this paper proposes an intelligent payment model based on asymmetric encryption. We use asymmetric encryption technology to constrain and force counterparties to give up collusive behavior, so as to ensure that all parties cannot collude under rational circumstances. We also provided mathematical proofs and contract implementations in Solidity. Finally, the simulation experiment verifies the superiority of our method. Compared with the traditional tower observation mechanism, our scheme can improve the accuracy by 13% on average.
