Abstract

The invention relates to the field of information security, in particular to a key management, data encryption and identity authentication method oriented to an electrical measuring instrument. The method is remarkably characterized in that an asymmetrical encrypting-decrypting mechanism is adopted, and executed by two independent servers; a main server is used for generating and managing public and private keys; and an auxiliary server is used for decrypting a random number sequence generated by the electrical measuring instrument and transmitting the random number sequence to a monitoring center, so that the security of an incredible or unreliable communication transmission link is enhanced. The robustness of information security guarantee is enhanced through electrical energy instrumentidentity authentication based on an OCSVM (One-Class Support Vector Machine) algorithm, and extra processing overhead does not need to be increased. The method can be implemented with limited storageresources and computation capability of the electrical measuring instrument.

Description

Technical field [0001] The present invention relates to the field of information security, and more specifically, to a method for key management, data encryption and identity authentication for power measuring instruments. Background technique [0002] The smart grid is a 3S system that combines the electric power system (Electric Power System, EPS), the information communication system (Information Communication System, ICS), and the monitoring control system (Monitoring Control System, MCS). The EPS is composed of power generation equipment, transmission and distribution Power Physical Network (PPN) composed of power infrastructure such as power grids and energy storage equipment, while ICS and MCS are composed of advanced sensing and detection technology, network communication technology, computer technology and intelligent control technology and other information infrastructure Power Information Network (PIN), the two are interdependent and deeply integrated to form a binary ...
