基于DBMS内核加密一卡通数据研究与实现

一卡通系统传输与采集的数据作为高机密的文件而存在高校服务器数据库中,为各客户端的应用提供了后台保障.如何保证一卡通系统中数据的安全已经成为高校及一卡通集成商研究与解决的难题之一.针对此,文中提出基于DBMS内核的加密模式与算法,实现一卡通数据在加密存储和高效查询上得到双重保证,使高机密性数据安全存储与访问通过高强度的静态保护设计与运行时动态保护设计双重结合,有效地防止重放攻击、替换攻击.

Implementation of Data Encryption based on DBMS Kernel

Packaged campus card system plays an extremely important role in university digital campus, and how to ensure the data security becomes a difficult problem of the universities and even card integrators. So this paper proposes an encryption model and algorithm based on DBMS kernel, thus to achieve dual assurance of the data encryption in storage and efficient query.
