Abstract: Transposition Cryptosystem has a rather long history. It makes up of the three essential cryptosystems together with substitution and Vingenere. Although transposition cryptosystem is gradually being neglected by some modern cryptographer on modern cipher scheme designing, it may still has some vitality if the designers prefer to adopt it. And transposition permutations can befittingly be used in the design of modern bloke cipher.

Key words: transposition cryptosystem, transposition-based bloke cipher scheme
