Information security management module of intelligent gas meter

Abstract

The invention discloses an information security management module of an intelligent gas meter, and belongs to an auxiliary device of intelligent gas meter management. 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 with the first data interface, a second data interface and the FLASH memory; identity authentication is carried out when the information security management module exchanges data with an external data sending terminal, so that the legality of communication between the information security management module and the external data sending terminal is ensured, and a main controller of an intelligent gas meter terminal can be communicated with the outside only through the information security management module; and the authorization setting of hierarchical management in a gas company can be realized by utilizing different keys, and a manner of 3DES (Triple Data Encryption Algorithm) / AES (Advanced Encryption Standard) multi-stage encryption is adopted, so that the security of the keys is higher, the keys can be updated in real time through a program download port on the information security management module, and the risks caused by leakage of the keys are avoided. The information security management module is simple in structure, can ensure the independence of the gas company on gas meter control, and is not restricted by the outside.
