摘要
在高校校园一卡通运行环境中,对校园卡卡片和数据传输两方面的安全进行深入的分析。结合传统密码算法和现代密码算法实现各级密钥的生成和分发,以传统的3DES加密算法生成各级密钥,以现代密码技术PKI技术实现会话密钥的分发,并对整个校园卡一卡通的密钥管理方案进行具体的设计。
Based on campus ecard system,a profound analysis in security of card and data transmission has been made.A method which uses traditional 3des cryptogrammic arithmetic to generate key has been presented.And modern cryptogrammic arithmetic(PKI)has been used to distribute session key.At last,a detailed key management plan has been proposed.
