Permutation/Transposition Cryptography
Permutation/Transposition Cryptography is a #Cryptographic method that encrypt a message by rearranging the plaintexts. This includes changing Encoding# system of the plaintexts. Since it doesn’t alter the frequency of letters from the original plaintext, it is vulnerable to Frequency Analysis#. It is even more dangerous to group the ciphertext in group that match the key size used by the cipher.
