English Description：
Transposition cipher is the pure text message of cipher, which can reach agreement between sender and receiver through some method. In this paper, we study the transformation, affine and substitution of mono alphabetic transposition ciphers. The letter of the mono alphabetic password is changed by creating a new letter (password letter) and assigning a new letter. In transposition password, there is no creation of new alphabet of letters in plaintext, just rearrange some fashion. In simple columnar interchange, the information is written in fixed and horizontally agreed number of columns, and then the description of the letter column proceeds from left to right.
