基于智能卡的多表一卡管理系统的研究

Study on Managing System of More-meter-one-card Based on CPU Card

设计和开发了水、电、气多表一卡管理系统,该系统采用一块CPU卡成功实现水、电、气多表数据的综合管理。由于采用CPU卡的密钥管理方式,以及对数据库的读写操作进行了权限控制,使系统的安全性能得到了有效的保证。

This system realizes the comprehensive management about water, electricity and gas with one CPU card, The system security is guaranteed by using secret key to manage and control popedom to read-write program of database.
