加密算法采用CBC分组模式加密，将输入的32bit明文序列先与上一次密

The encryption algorithm adopts CBC packet mode encryption. The input 32-bit plaintext sequence is first XORed with the last ciphertext (when the plaintext sequence is first input, it is XORed with the 32-bit initial vector). Each of the entire ciphertext sequence is individually encrypted. The grouping has a stronger correlation with the ciphertext of the previous group, so as to eliminate the statistical law between the plaintext and the ciphertext sequence, and enhance the confusion and diffusion characteristics of the algorithm.

Encryption algorithm using CBC grouping mode encryption, the input of 32bit clear text sequence and the last redaction of the first different or operation (the first input of the clear text sequence, with the initial vector of 32bit is different or), the entire redaction sequence of each individual encrypted grouping with the previous group of redaction has a stronger correlation, so as to eliminate the statistical law between clear text, redaction sequence, enhance the algorithm confusion and diffusion characteristics.

In this algorithm, the difference between the input ciphertext sequence and the original ciphertext sequence will be enhanced Confusion and diffusion characteristics.<br>
