Integrated circuit (IC) card intelligent gas meter information safety management module

Abstract

The invention discloses an integrated circuit (IC) card intelligent gas meter information safety management module, and belongs to IC card intelligent gas meter management auxiliary devices. The information safety management module comprises a processer, a first data interface, a second data interface and a FLASH memorizer, wherein the processer is respectively switched in the first data interface, the second data interface and the FLASH memorizer, identity authentication is conducted to a gas selling management system by the information safety management module through an IC card information exchange module in the process of conducting data exchanging with the gas selling management system, and therefore validity of communication between the information safety management and the gas selling management system is guaranteed. Level-to-level administration to a gas company is achieved by utilizing different secret keys, a manner of 3 data encryption standard (DES) or advanced encryption standard (AES) multilevel encryption is adopted, safety of the secret keys is high, the secret keys can be updated in real time through a program download interface of the information safety management module, and therefore the risks caused by exposure of the secret keys are avoided. The IC card intelligent gas meter information safety management module is simple in structure, independence of an energy company in gas meter control is guaranteed, and restriction from the outside world is avoided.

Description

technical field [0001] The invention relates to an IC card smart gas meter management auxiliary device, more specifically, the invention mainly relates to an IC card smart gas meter 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 smar...
