Abstract

Eavesdroppers are constantly trying to reveal encrypted messages sent within communication channels. The motive to illegally decrypt ciphertexts (encrypted messages) could be for economical, security or political reasons. Finding secured way of protecting ciphertexts from being stolen and revealed, has been very challenging for existing cryptographic researchers. This paper proposes a novel method to protect the ciphertext by replication the original plaintext (unencrypted messages) by altering them before encrypting them and then send the ciphertexts through the communication channel. In the communication channel, if an eavesdropper attempt to intercept the ciphertext, the listener is subjected to large range of guesses, of which ciphertext is the right one to perform cryptanalysis. When the Eavesdropper is subjected to large range of guess work, the process of cryptanalysis is made more difficult. Increasing the difficulty in cryptanalysis as a result of subjecting the Eavesdropper to large range of guessing is believed to be a promising technique of securing a message in a cryptographic system.
