随着密码分析技术的提高，新的数据加密标准AES取代了过时的DES。文章在阐述AES/RSA加密算法的基础上，分别给出了利用AES/RSA实现客户端/服务器端网络数据传输的加密流程。最后在比较AES算法和RSA算法基础上，将AES与RSA相结合提出一种新的数据加密方案。-analysis technology improvements, new data encryption standard AES replaced the outdated DES. The article described AES/RSA encryption algorithm on the basis of the difference is the use of AES/RSA achieve client/server network data encryption process. Finally in comparison AES and RSA algorithm, based on AES and RSA will be combined, a new data encryption program.
