基于人工免疫理论的数据保密通信研究

针对数据保密通信的现实需求,提出一种新的保密通信方法.该方法首先基于否定选择算法从明文信息本身提取加密因子,然后再以加密因子按m序列进行密钥扩展,生成伪随机密钥序列对明文进行加密.利用该方法生成的伪随机密钥序列的自相关特性较好,数据加密后具备了较好的抗攻击性能,同时接收端还可以用加密因子进行免疫鉴别,以检验数据的完整性.

Data Security Communications Based on Artificial Immunity Theory

For the realistic demand of data security communications,a new security communication method was proposed.First of all,the encryption factor was extracted from the plaintext.Secondly,Encryption factor as a key group was expanded by the way of the m-sequence and generates pseudo-random key sequence that can be used to encrypt data.Pseudo-random key sequence generated in this way had good characteristics of self-correlation and the encrypted data had a better anti-attack performance.Meanwhile,the receiver can...
