Data Security Communications Based on Artificial Immunity Theory
Tao Li · Journal of Sichuan University · 2010
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.
