Dr G R D College of Science – CBE Since it does not, we will assume the keyword, used in the columnar transposition has one less, letter, that is, we assume that it is 7 letters, Then the keyword columnar transposition will, which says that the digraphs TL and HY occur in, the ciphertext. Trudy is our generic 'intruder' ... Good Guys and Bad Guys. In the cryptography system, a transposition cipher is a method of encryption by changing the position of plain text into different position. Decipher this, Solution In the deciphering process, we will, encipher the message in the keyword columnar, transposition is shorter than the known word, (crib) given in the plaintext. They also noted that re-encrypting the cipher text using same transposition cipher creates better security. A study of these techniques enables us to illustrate the basic approaches to symmetric encryption used today and the types of cryptanalytic attacks that must be anticipated. A .
