摘要
近年来,由于全球信息化发展的日益加剧,以及国家"金卡工程"发展的不断深入,智能卡的广范应用成为一种趋势。智能卡的广范应用给我们带来的便捷与时尚是显而易见的:人们不用随身带着大把的现金出门购物;不用再为找零钱而浪费宝贵的时间。当然,智能卡为人们的生活增添便捷的同时,也为交易注入了保障,比如在防范假钞、防止偷盗等方面的贡献,进而使人身安全威胁和经济损失的可能性大大减少。智能卡能否出色完成它的使命,则决定于卡片本身的安全系数,即智能卡内密钥的安全性,正是为了更好的维护和保障这些密钥的安全,文章设计了一个基于智能卡的、存储并管理密钥的密钥管理系统。
In recent years,due to the increasing development of the global information,as well as the national" Golden Card Project",the smart card is widely used as a prevailing trend.It is obvious that the smart card has brought us convenience and fashion: people don't have to carry a lot of cash to go for a shopping and waste our valuable time on changing.Of course,the smart card not only brings our life much convenience,but also supplies with security,such as the contribution in the prevention of counterfeit money and theft,so that the personal safety and economic losses are significantly reduced.Whether or not can smart card accomplish its mission,depending on the safety of card itself,namely the key security in the smart card.In order to make a maintenance and protection for security of the keys,this paper designs a key management system based on smart card to store and manage the keys.
