IC (integrated circuit) card intelligent heat meter with embedded information security management module

Abstract

The invention discloses an IC (integrated circuit) card intelligent heat meter with an embedded information security management module. The IC card intelligent heat meter comprises the information security management module. The information security management module comprises a processing unit, a first data interface, a second data interface, and a flash memory. The processing unit is connected to the first data interface, the second data interface and the flash memory. The information security management module authenticates the identity with a heat sales management system through an IC card reading module during data exchange, so that validity in communication between the information security management module and the heat sales management system is guaranteed, and a terminal master controller of the IC card intelligent heat can be communicated with the outside only through the information security management module. Permission setting for level-to-level administration in heat energy companies can be realized through different keys; by means of 3DES / AES multilevel encryption, the keys can be upgraded in real time through a program downloading port of the information security management module, and risks caused by key leaking are avoided; independency of controlling the heat meters is guaranteed for the energy companies with no limits from outside.

Description

technical field [0001] 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 [0002] 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 management methods of IC card smart heat meters, and different brands of IC card smart heat meters use different management systems, operating equipment, transmission media, Management passwords and operation meth...
