摘　　要：随着经济的发展,企业积累的重要数据和信息资源日益丰富,因此对文件加密技术提出了更高的要求。AES性能优越,但也存在种子密钥单一和密钥空间固定等问题。论文将混沌理论中的二维Logistic映射方法应用到AES的加密算法中,利用其初值敏感性和不可预测性改善了扩展密钥的构造质量,增强了AES算法的安全性,起到了显著的优化效果。With the development of economy,the important data and information resources accumulated by enterprises are becoming more and more abundant,which puts forward higher requirements for file encryption technology.AES has excellent performance,but there are also some problems such as single seed key and fixed key space.In this paper,the two-dimensional Logistic mapping method in chaos theory is applied to AES encryption algorithm,and its initial value sensitivity and unpredictability are used to improve the quality of extended key construction,enhance the security of AES algorithm,and remarkable optimization results are obtained.
