Integrated circuit (IC) card intelligent gas meter embedded with information security management module

Abstract

The invention discloses an integrated circuit (IC) card intelligent gas meter embedded with an information security management module. The IC card intelligent gas meter comprises the information security management module. The information security management module comprises a processor, a first data interface, a second data interface and a flash storer, wherein the processor is respectively connected into the first data interface, the second data interface and the flash storer. When the information security management module exchanges data with a gas sale management system through an IC card read module, identity authentication is conducted, and the communicating validity of the information security management module and the gas sale management system is ensured. A terminal master controller of the IC card intelligent gas meter can be communicated with the outside only through the information security management module. Permission setting of level-to-level administration of gas companies can be achieved by using different secret keys, and moreover, a 3 data encryption standard / advanced encryption standard (3DES / AES) multilevel encryption mode is adopted, the secret keys can be updated in real time through a program download port on the information security management module, and risks caused by leakiness of the secret keys are avoided. Meanwhile, the IC card intelligent gas meter embedded with the information security management module can guarantee the independence of gas meter control of the gas companies, and restrictions from the outside can be avoided.

Description

technical field [0001] The invention relates to an intelligent gas meter, more specifically, the invention mainly relates to an IC card intelligent gas meter embedded with an information security management module. Background technique [0002] There are various kinds of IC card smart gas meters on the market, and the quality is uneven. Various gas companies have not yet summarized the identification methods and selection standards, resulting in some gas companies using at least a few brands, and at most dozens of brands. IC card smart gas meters, manufacturers of IC card smart gas meters use different management methods for IC card smart gas meters and have their management methods in their hands. The gas companies do not have control over IC card smart gas meters technically. IC card smart gas meter manufacturers can separate from the management system of the gas company, process the information of the IC card smart gas meter, and control the use of the IC card smart gas m...
