An ID-Based Linear Homomorphic Cryptosystem and Its Applications for the Isolated Smart Grid Devices

摘要

In this paper, we propose an ID-based linear homomorphic cryptosystem, which consisted of an ID-based encryption scheme with homomorphic property and a linearly homomorphic signature scheme, where the linearly homomorphic signature scheme is compatible with the privacy-protection data aggregation. Then, we propose a secure and efficient ID-based meter report protocol for the isolated smart grid devices, which can not only protect against unauthorized reading, unintentional errors and maliciously altering messages, but also achieve privacy-preserving for the customers. We provide security analysis of our protocol in context of five typical attacks. The implementation of our protocol on the Intel Edison Platform shows that our protocol is efficient enough for the physical constrained devices, like smart grid devices.
