摘要:

网络信息安全关系到数据存储安全和数据通信安全,为了提高网络信息安全管理能力,需要进行数据优化加密设计,提出一种基于前向纠错编码的DES数据公钥加密技术,采用Gram-Schmidt正交化向量量化方法构建DES数据的Turbo码模型,通过三次重传机制产生密文序列,对密文序列进行前向纠错编码设计,结合差分演化方法进行频数检验,实现网络信息安全中DES数据加密密钥构造,选择二进制编码的公钥加密方案有效抵抗密文攻击；仿真结果表明,采用该加密技术进行DES数据加密的抗攻击能力较强,密钥置乱性较好,具有很高的安全性和可行性。

Abstract:

Network information security related to the data storage security and data communication security, in order to improve the network information security management capabilities, the need for data encryption optimization design, this paper puts forward a DES public key data encryption technology based on forward error correction encoding before the construction of DES data using Gram-Schmidt orthogonal vector quantization method of Turbo code model to produce ciphertext sequence by the three retransmission mechanism, the ciphertext sequence of FEC encoding design, combined with the differential evolution method of frequency test, the realization of DES data encryption key structure in network information security, public key encryption scheme to choose binary encoding resist ciphertext attack. The simulation results show that the encryption technology used in DES data encryption has strong anti attack ability, good scrambling key, high security and feasibility.
