加密算法在大容量智能卡上的应用

摘要

Along with the application of smart card,it becomes more and more important for card data security. If the card data can not get effective protection,business development will be restricted. So it is an urgent problem for operators to ensure the card data security. This paper analyzes the security policy for the large-capacity smart card,and recommendates the encryption algorithm for operators to develope the large-capacity smart card business.%随着大容量智能卡的推广应用，卡数据的安全问题越来越重要，如果卡数据得不到有效的防护，将制约业务的开展，甚至造成用户财产的损失，因此保证卡数据安全是运营商急待解决的问题。本文分析了目前适用于大容量智能卡上的安全策略，并对运营商开展大容量卡业务时需要用到的加密算法提出建议。
