中文摘要: 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。
Abstract: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 also use encryption factor to identify the integrity of the data.
