摘要
对于局域网内的数据传输,传统的DES、RSA加密算法在安全性和加密效率上都有所不足。提出一种基于3DES-DH混合的数据加密方法,旨在增强数据传输的安全性,同时尽量减少数据加解密带来的时间开销对传输效率的影响。为证明该方法的有效性,设计局域网数据传输的应用环境,实验测试与分析证明,该方法是一种有效可行的局域网数据传输加密方案。
For the data transmission in local area network, the traditional DES and RSA encryption algorithm are inadequate in security and effi-ciency. Presents a hybrid data encryption method based on the 3DES-DH, in order to enhance the security of data transmission and reduce the data encryption time cost and the effect of transmission efficiency. To demonstrate the effectiveness of the method, designs the application environment of the LAN data transmission. Test and analysis proves that this method is a feasible and effective LAN data transmission encryption scheme.
