Integrated circuit (IC) card intelligent electric energy meter embedded with information safety management module

Abstract

The invention discloses an integrated circuit (IC) card intelligent electric energy meter embedded with an information safety management module. The IC card intelligent electric energy meter comprises the information safety management module, wherein the information safety management module comprises a processor, a first data interface, a second data interface and a flash memory, the processor is respectively connected with the first data interface, the second data interface and the flash memory, the information safety management module carries out the identity authentication when exchanging the data with an electric energy management system through an IC card reading module, the communication legality between the information safety management module and the electric energy management system is guaranteed, and a terminal main controller of the IC card intelligent electric energy meter is communicated with exterior only through the information safety management module; the right setting of grading management of an electric power company can be realized by utilizing different keys, by adopting a 3 data encryption standard / advanced encryption standard (3DES / AES) multilevel encryption way, the key can be upgraded in real time through a program downloading port on the information safety management module, and the risk caused by the leakage of the key can be avoided; and meanwhile, the independence of the energy company on the aspect of controlling the terminal electric energy meter can be guaranteed, and the energy company is free from being restricted by the exterior.

Description

technical field [0001] The invention relates to an intelligent electric energy meter, more specifically, the present invention mainly relates to an IC card intelligent electric energy meter embedded with an information security management module. Background technique [0002] In recent years, with the continuous development of electronic technology and related technologies, IC card smart energy meters have been widely used, and various brands of IC card smart energy meters have appeared on the market. In order to facilitate the use and management, the power company began to adopt IC card smart energy meters, and built its own management system on this basis. Since the same power company may use multiple brands of IC card smart energy meters, each manufacturer independently masters the management methods of IC card smart energy meters. Different brands of IC card smart energy meters use different management systems, operating equipment, transmission media, The management pas...
