Research On Security Schemes Of Aggregation And Targeted Broadcast In Smart Grid

Smart grid integrates the communication network and remote terminals, such assmart meters, so that the smart grid enables two-way communication between thecontrol center and remote terminals to achieve the optimization of energy transmissionand distribution. However, These new features of the smart grid bring new problemsabout privacy protection and information security.Combining the characteristics of the smart network as well as the scene of datacollection, based on pseudonym, homomorphic encryption and identity-based aggregatesignature, this paper proposes an aggregation scheme in smart grid which can transmitdata between remote terminals and the control center securely and protect uses’ privacy.This paper also analyzes the security and performance of the scheme.Combining the scene of broadcasting data in the smart grid, using attribute-basedencryption and identity-based signature, this paper proposes a security scheme oftargeted broadcast so that the control center can targeted broadcast control data toremote terminals. This paper also analyzes the security and performance of the scheme.The two security schemes of aggregation and targeted broadcast in the smart gridwhich this paper proposes can be used as a complete two-way secure communicationsolution.
