Information safety management module for intelligent IC card water meter

Abstract

The invention discloses an Information safety management module for an intelligent IC card water meter, and belongs to an auxiliary device for the intelligent IC card water meter management. The information safety management module comprises a processor, a first data interface, a second data interface and a FLASH memory, wherein the processor accesses the first data interface, the second data interface and the FLASH memory. The information safety management module performs identity certification during data exchange with a water sale management system through an IC card information exchange module, thereby guaranteeing the legality of the communication; different secret keys can be used for realizing the level-to-level administration of a running-water company; multilevel encryption modes including a 3DES (triple data encryption algorithm) and AES (advanced encryption standard) are adopted, so that the security of the secret keys is higher, further, the secret keys can be upgraded in real time through a program downloading port in the information safety management module, and the risk caused by secret key leakage is avoided; and meanwhile, the modular structure is simple, the independence of water meter control can be guaranteed for the running-water company which is not limited by the outside.

Description

technical field [0001] The invention relates to an IC card intelligent water meter management auxiliary device, more specifically, the invention mainly relates to an IC card intelligent water meter information security management module. Background technique [0002] In recent years, with the continuous development of electronic technology, it has been widely used in various fields. Various manufacturers have gradually applied electronic technology to conventional water meters to produce various brands of IC card smart water meters. In order to facilitate the use and management, the water company began to adopt IC card smart water meters, and built its own management system on this basis. Since the same water company may use multiple brands of IC card smart water meters, each manufacturer independently masters the management methods of IC card smart water meters. Different brands of IC card smart water meters use different management systems, operating equipment, transmissio...
