摘　　要：随着无线传感器网络(WSN)在军事、医疗等敏感领域的广泛应用,其数据安全问题日益突出,而WSN节点资源限制使得传统加密算法难以高效实现。本研究针对WSN特点,对高级加密标准(AES)进行了深入分析和改进,提出了轻量级高级加密标准(LAES)算法。LAES采用优化的S盒、7轮结构和全局查表法,在理论分析和实验评估中均表现出优异性能。结果显示,LAES在保持高安全性的同时,执行速度提升了30%,RAM占用减少了39%,为WSN数据安全提供了切实可行的解决方案。With the widespread application of wireless sensor networks(WSN)in sensitive fields such as military and medical,data security issues have become increasingly prominent.However,the resource limitations of WSN nodes make it difficult to efficiently implement traditional encryption algorithms.This study conducted an in-depth analysis and improvement of the Advanced Encryption Standard(AES)based on the characteristics of WSN,and proposed the Lightweight Advanced Encryption Standard(LAES)algorithm.LAES adopts an optimized S-box,7-wheel structure,and global lookup table method,which has shown excellent performance in both theoretical analysis and experimental evaluation.The results show that LAES maintains high security while increasing execution speed by 30%and reducing RAM usage by 39%,providing a practical solution for WSN data security.
