摘要：
An improved stream cipher based on the linear feedback shift register is set up by adding disturbance on to the initial states. The key advantage of the new algorithm over the already proposed ones is that the characters of the ciphertext corresponding to the same characters in the plaintext are distinct. The new algorithm also keeps all other advantages. Therefore, for the adversary, it is more difficult to make an attack by analyzing the statistics data of the characters.
