Information security management module of IC (integrated circuit) card intelligent heat energy meter

Abstract

The invention discloses an information security management module of an IC (integrated circuit) card intelligent heat energy meter and belongs to a management auxiliary device of the IC card intelligent heat energy meter. The information security management module comprises a processor, a first data interface, a second data interface and a FLASH memory, wherein the processor is respectively connected into the first data interface, the second data interface and the FLASH memory, and the information security management module is used for performing identity authentication when performing data exchange with a heat energy selling and management system through an IC card information exchange module, thereby ensuring the legality of communication between the information security management module and the heat energy selling and management system; different keys are used for realizing staged management of a heat energy company, a 3DES / AES (triple data encryption standard / advanced encryption standard) multi-stage encryption way is further adopted for realizing relatively high security of the keys, and the keys are upgraded in a real-time manner through a program downloading port on the information security management module to avoid the risk caused by leakage of the keys; and meanwhile, the module disclosed by the invention has a simple structure, can ensure the independency of the energy company in control of the heat energy meter, and is not restricted by the outside.
