Abstract:In cryptography, the security is depending on the way in which it produces different ciphertexts for the same plaintext so that the eavesdropper is not able to recover the plaintext from the ciphertext. Though, several block cipher modes viz., CBC, CFB and OFB exist, they take more time for producing different ciphertext blocks for the same plaintext block. To avoid this, an encoding is performed at the plaintext level. There are several encoding schemes like ASCII, Magic Square, and Magic Rectangle based enco… Show more
