校园一卡通系统中密钥管理系统的设计与实现

Design and Implementation of Key Management System of Campus E-Card System

以密钥管理在校园一卡通系统中的应用为中心,研究密钥管理系统在一卡通系统中的具体应用模式,并在校园一卡通项目中实现了密钥管理。首先以IC卡技术和密码算法技术为基础,提出了一卡通系统的密钥管理系统的解决方案;然后针对系统的实现,详细描述了密钥分散的设计和实现过程;最后对系统中使用的算法进行了描述和安全性分析。

Through an application example of key management system in campus E -card system,this paper studies the specific application mode,and the key management has been used in Campus E- Card project. On the basis of smart card technology and encryption algorithm,this paper first presents the solution of key management system of Campus E -Card system,and then gives a detailed description of design and implementation process of encryption key diversify,and discusses the algorithm used in the system and studies the security.
