提出了一种基于混沌流密码的IC卡数据加密算法,利用混沌系统的类随机性和难以预测性特点,实现了智能卡信息的有效加密,从而保障了IC卡信息的数据安全,并成功将该方法应用到了智能仪表中,取得了良好的效果。
A novel data encryption for IC card based on chaotic stream ciphers is proposed. As behaviors of chaotie systems are random and unpredictable,it is used to implement encryption algorithm for data of IC card, and so the data on IC card become very safe. The method is used in intelligent instruments and has been tested to be effective.
