摘要
提出了一种基于电子钥匙的双向身份鉴别方案。首先调用电子钥匙内嵌的软硬件接口函数,生成硬件随机数,然后更新密钥,并对时间戳和随机数等身份鉴别信息按数据加密标准、安全散列算法进行加/解密和散列运算。分析结果表明该方案具有较强的安全性,可以有效地防止密钥泄漏、重放攻击和假冒攻击。
A mutual authentication scheme using USB KEY is proposed. USB KEY generates random numbers, updates keys and operates authentication information composed of random numbers and time stamps using its software and hardware inbuilt interface functions. The scheme has strong security, and it can avoid key-lost, replay attack and impersonation attack effectively.
