IC card intelligent heat energy meter embedded with information safety management module

Abstract

The invention discloses an IC card intelligent heat energy meter embedded with an information safety management module. The IC card intelligent heat energy meter embedded with the information safety management module comprises the information safety management module which comprises a processor, a first data interface, a second data interface and a FLASH storage, wherein the processor is respectively connected into the first data interface, the second data interface and the FLASH storage. The information safety management module conducts identity authentication when an IC card reading module and a heat energy sales management system exchange data so that the legality of the communication between the IC card reading module and the heat energy sales management system can be ensured. A terminal master controller of the IC card intelligent heat energy meter must be communicated with outside through the information safety management module. The permission setting of hierarchical management of a thermal energy company can be realized through the utilization of different secret keys. The secret keys can be updated in real time through the adoption of multi-level encryption ways of 3DES / AES and the program load port of the information safety management module so that risks caused by the secret key exposure can be avoided. Meanwhile, the IC card intelligent heat energy meter embedded with the information safety management module can ensure the independence of the terminal heat energy meter control of an energy company and is not limited by the outside world.

Description

[0001] This invention is a divisional application filed by the applicant based on another invention patent that he previously applied for. IC card smart water meter with information security management module. technical field [0002] The invention relates to an intelligent heat energy meter, more specifically, the invention mainly relates to an IC card intelligent heat energy meter embedded with an information security management module. Background technique [0003] In recent years, with the continuous development of electronic technology and the widespread use of IC card smart heat meters, many different brands of IC card smart heat meters have appeared on the market. In order to facilitate the use and management, the thermal energy company began to adopt IC card smart heat energy meters, and built its own management system on this basis. Since the same heat energy company may use multiple brands of IC card smart heat meters, each manufacturer independently masters the m...
