校园一卡通密钥管理的设计与实现

Design and Implementation of Key Management in Campus Card

校园一卡通既满足学校现代化管理的需要,又满足师生日常生活的多种需求,其电子管理功能块将使学校实现电子化管理,提高工作效率,加强校园管理,但其电子钱包的安全性是一卡通应用的保障基础.以IC卡技术和密码算法技术为基础,提出了一卡通中密钥管理系统的解决方案,以根密钥、母密钥和用户密钥三层密码机制来充分保障密码生成、保存以及IC卡使用的安全.

Campus card serves the modern campus management and the various needs of faculty and students.Its egovernance will help the realization of electronic management of schools, improve efficiency and strengthen school management on the basis of the security of e - purse Card Application. IC card technology and technology - based cryptographic algorithm are the key to the card management system, combining the three - tier mechanism （the root key, home key and the user password key） to generate adequate protection of the IC card.
