Abstract

The invention discloses an information security management module for an integrated circuit (IC) card intelligent ammeter and belongs to IC card intelligent ammeter management auxiliary devices. The information security 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. Identity authentication is performed when the information security management module performs data exchange with an electricity selling management system through an IC card information exchange module, and legality of communication between the information security management module and the electricity selling management system is guaranteed; grading management of electric power companies can be achieved by utilizing different secret keys; a triple data encryption standard / advanced encryption standard (3DES / AES) multistage encryption mode is adopted, so that safety of the secret keys is safe; the secret keys can be updated in real time through a program download port positioned on the information security management module, and risk caused by secret key leakage is avoided. Simultaneously, the information security management module is simple in structure, can guarantee independence of energy companies on ammeter control and is not subjected to outside restriction.

Description

technical field [0001] The invention relates to an IC card intelligent electric energy meter management auxiliary device, more specifically, the present invention mainly relates to an IC card intelligent electric energy meter information security management module. Background technique [0002] In recent years, with the continuous development of science and technology, various manufacturers have developed various brands of IC card smart energy meters and put them into production in large quantities. Power companies have adopted a large number of IC smart energy meters as terminal metering equipment, and built their own management systems 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, Management passwords, op...
