Sequence encryption method based on negative selection algorithms

For high safe and high efficiency encryption system was designed by using the negative selection algorithms of Artificial Immunity Theory, and its safe was demonstrated. It is a new method based on the negative selection algorithm and extracts the encryption factor from the plaintext. Encryption factor as a key group is 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 has good characteristics of self-correlation and the encrypted data has a better anti-attack performance. Therefore, there will be a good prospect of application.
