Security data reporting method and security data reporting system on basis of Hash trees and anonymity technologies

Abstract

The invention discloses a security data reporting system on the basis of Hash trees and anonymity technologies. The security data reporting system comprises four parties and seven modules. The four parties include a trusted authority (TA), a control center (CC), a gateway (GW) and a residential area (RA), and the gateway (GW) is connected with the trusted authority (TA) and the residential area (RA); the seven modules include a system initialization module, a session key agreement module, an autonomous aggregation forming module, an offline pre-computation module, an online power consumption data reporting module, a security data collecting module and a security data reading module. The security data reporting system has the advantages that the light-weight security data reporting system can be applied to intelligent power grids, accordingly, the privacy can be protected, and the integrity of communication data can be guaranteed.

Description

technical field [0001] The invention is applied to the field of smart grids, and specifically relates to a security data reporting method and system based on a hash tree and anonymous technology. Background technique [0002] The smart grid is regarded as the next generation grid system, because the smart grid is based on the information-physical architecture and integrates the new generation of information and communication technologies, such as figure 1 As shown, the electric energy supplier can monitor, control and predict the generation and consumption of electric energy efficiently and in real time. At the same time, users can obtain power prices and power management information from the smart grid in real time, so as to make reasonable decisions and greatly reduce household power consumption. However, in the smart grid, the user's power consumption data contains sensitive information such as the user's daily habits, and high-frequency collection of user's power consum...

Problems solved by technology

So the MAC / HMAC method still has very complex computation and communication overhead

Therefore, in the smart grid with sensitive delay and limited communication resources at the user end, it is urgent to design and implement a secure (privacy protection, authentication, data integrity) and efficient communication protocol and application system, and fully consider the smart meter and other equipment The actual situation of limited hardware (storage, computing) and communication resources; in addition, smart grid end users usually have an uncertain topology, and existing application systems rarely consider the dynamic characteristics of end users, and do not support flexible and autonomous methods Data reporting, resulting in theoretical methods that are not suitable for practical application environments
