摘　　要：为提高抗攻击性能,设计复杂电力物联终端多维数据的轻量级分组密码算法。利用STCS混沌映射生成轻量级分组密码算法核心部件S盒,设计算法核心部件P盒,基于广义Feistel结构的轻量级分组密码算法,将复杂电力物联终端多维数据分成四个相同数据子块后,利用1个P盒实现S盒混淆层16比特输出结果的线性变换,实现多维数据的轻量级分组加解密。实验结果表明,该密码算法具有较高的密钥敏感性,非加密密钥无法实现电力物联终端多维数据的正确解密;最大安全强度可达到90.8%,2 048长度数据加密仅需16 ms,且具有抗攻击性能。In order to improve anti-attack performance,a lightweight block cipher algorithm for multidimensional data of complex power iot terminal is designed.STCS chaotic mapping is used to generate the core component of lightweight block cipher algorithm S box,and the core component of the algorithm P box is designed.The lightweight block cipher algorithm based on generalized Feistel structure divides the multi-dimensional data of complex power Internet of Things terminal into four identical data subblocks,and uses one P box to realize the linear transformation of the 16 bit output result of the confusion layer of S box.Lightweight group encryption and decryption of multidimensional data is realized.The experimental results show that the cryptographic algorithm has high key sensitivity,and the non-encryption key cannot decrypt the multi-dimensional data correctly.The maximum security strength can reach 90.8%,2048 length data encryption only needs 16 ms,and has anti-attack performance.
