摘　　要：传统的网络数据加密机制是通过对明文、密文的加解密来抵抗网络空间里未知的网络攻击;但面对庞大的网络数据量,特别是复杂的网络数据报结构及自相关性强烈的网络数据,传统的网络数据加解密机制由于存在密钥空间狭小与序列混乱度不高等弊端,难以有效保护高度冗余数据传输;对此提出一种新的基于迭代技术的网络数据加密机制来改善这一问题,通过将迭代机制引入到网络数据加密机制中,从数学上验证改进后的网络加解密机制对大数据量条件下,新机制对高度冗余数据最易遭受的明文攻击有着良好的鲁棒性;然后对提出的新机制进行了仿真实验验证,结果表明:在最易遭受明文攻击的复杂结构网络数据的传输中,新机制不但能够显著提高抵御明文攻击性能,而且统计学特性也得到了改善。The traditional network data encryption mechanism resists the unknown network attacks in the network space through the encryption of plaintext and ciphertext, but it has some obvious defects such as small key space, low chaotic sequence and low speed of encryption and decryption in face with the numerous data, especially complex data structure and data with strong self-correlation. So, the new network data encryption mechanism based on iterative technology was proposed to solve this problem. By taking the iteration mechanism into the network data mechanism, and demonstrated the improved network data mechanism by mathematically, it showed that： under the condition of huge amount of data, the new mechanism proposed by the paper can resist the attacks for the most vulnerable plaintext from the network data well. And then conducting the simulation experiments, the results showed that： the networks data transmission of the most vulnerable plaintext attack in the complex network data structure, and the new mechanism proposed by paper not only can improve the property of resisting the plaintext attacks, but also improve the statistical characteristics as well as the speed of encryption and decryption speed in certain extent.
