Application of hybrid cipher algorithm to water information transmission

对称密码和非对称密码相结合的混合密码算法以其较快的速度和较高的强度提供了信息的完整性和保密性等功能,在基于VPN的网络安全中起着重要的作用。研究讨论该混合加密算法的实现机制,并在VC++6.0平台下进行编程已实现该算法。通过系统安全性分析和工程实践检验,基于AES和ECC的混和加密算法比传统的DES算法和RSA算法具有更高的安全性,可有效地满足VPN网络对数据传输的安全需求。

The hybrid cipher algorithm combined with symmetric and asymmetric cipher algorithm has provided the functions of information integrity and secrecy with faster speed and higher intensity, which has played very important roles in the VPN network security, this paper discusses the implementation mechanism of this algorithm, and carries on the programming under the VC ＋＋ 6.0 platforms to realize this algorithm. Through the system safety analysis and the project practice examination, this algorithm based on AES and the ECC has a higher security compared with the traditional DES algorithm and the RSA algorithm, and satisfies the VPN network requirements effectively to the data transmission security.
