A Privacy-Preserving Aggregation and Authentication Scheme Towards Mobile Users in Smart Grid

doi:10.1007/s12204-019-2137-8

Abstract

Abstract: With the enormous development of imformation and communication technology, more concerns are focused to achieve secure and reliable smart grids as the social infrastructure, especially in the explosion era of mobile devices. In this paper, we propose an efficient scheme to satisfy the outdoor electrical demand of mobile customers. Our scheme protects the privacy and integrity of users' electricity consumption data. Technically, we encrypt users' electricity consumption data by a chosen-plaintext-attack (CPA) secure public key encryption (PKE) scheme and aggregate ciphertexts by the aggregator (an untrusted third party). In the scheme, internal and external adversaries cannot obtain the electricity consumption data. Additionally, we require users to provide authentication and commitment of consumption data that can track who modifies the data, which protects the integrity of users' electricity consumption data.
