随着物联网应用的普及,高效的轻量级分组密码对于保障资源受限设备的信息安全具有重要意义.本文提出一种高效的轻量级分组密码算法,命名为HBcipher. HBcipher分组长度为64位,密钥长度支持64位和128位.算***函数采用三组SPN结构的F函数,且在设计F函数时利用几何图形映射性质构造一种P2置换方法,充分隐藏明文的统计特性,提高抗统计分析的能力,为避免最后一轮完全暴露给攻击者,我们在最后一轮P2置换输出后,增加白化密钥加模块.同时,我们设计了一种动态轮密钥加运算操作,加密数据根据算***运算控制信号的奇偶性来动态选择更新后的子密钥,与一般静态密钥加相比,提高了算法灵活性和安全性,特别是抵抗...

With the popularity of IoT applications, it has a great significance to design efficient and lightweight block ciphers to ensure the information security for the resource-constrained devices. This study designs a high-efficiency lightweight block cipher named HBcipher. Its block length is 64 bits and it supports key lengths of 64 bits and 128 bits. The round function of HBcipher adopts three sets of F-functions of SPN structure, and constructs a new P2 permutation by using geometric mapping properties when designing the F-function, which effect...
