为保障数据库外层数据的安全传输,提出一种基于混沌序列和AES算法的数据库外层数据传输同步加密方法。该方法结合AES算法的加密安全性和混沌序列的加密速度优势,通过加密代理服务器和应用服务器对数据库外层数据进行处理,利用混沌序列logistic映射参数初始化、混沌序列二进制量化、AES动态加密和尾端处理实现数据库外层数据传输同步加密。实验结果表明,该方法能够成功地对文本和图像数据进行加密和隐藏,同时提高加密效率,并兼顾了数据的安全性和传输效率。

To ensure the secure transmission of outer data in the database,a synchronous encryption method for outer data transmission in the database based on chaotic sequences and AES algorithm is proposed.This method combines the encryption security of AES algorithm and the encryption speed advantage of chaotic sequences.It processes the outer data of the database through an encryption proxy server and application server,and uses chaotic sequence logistic mapping parameter initialization,chaotic sequence binary quantization,AES dynamic encryption,and tail end processing to achieve synchronous encryption of the outer data transmission of the database.The experimental results show that this method can successfully encrypt and hide text and image data,while improving encryption efficiency and balancing data security and transmission efficiency.
