Abstract

The invention discloses a decentralized access control method for safe sharing of data in a smart power grid. The method comprises the following main implementation steps: 1, constructing an access control system; 2, initializing an access control system, and generating a global public parameter GP of the system; 3, initializing an authorization mechanism; 4, generating a user key; 5, generating acloud server private key, a signature public key and a signature private key; 6, generating a final ciphertext; 7, verifying the identity of the user and decrypting the message; and 8, deleting the user to be revoked from the private key list of the cloud server. According to the method, multiple mechanisms are adopted to jointly undertake tasks of the system, the efficiency of the system is improved, a large amount of encryption and decryption calculation is carried out by the cloud server, the calculation overhead of a data user is saved, and zero knowledge is added to prove that the identity information of the user is protected in the interaction process of the user and multiple authorization mechanisms.

Description

technical field [0001] The invention belongs to the technical field of cloud storage security and information security, and in particular relates to a decentralized access control method for data security sharing in a smart grid. Background technique [0002] With the development of science and technology, smart grid emerges as the times require. It can both meet the power demand and integrate the power using the information network. The difference between smart grid and traditional grid is that it breaks the form of one-way information exchange and realizes two-way information exchange between users and power companies. The realization of this two-way information exchange enables the power supply company to generate electricity in real time according to user needs, and also allows users to collect and analyze the electricity consumption data of residential buildings in real time according to smart devices. The smart grid is divided into power flow and information flow, an...
