A MESSAGE ENCRYPTION TECHNIQUE COMBINING CAESAR CIPHER WITH ATBASH CIPHER

Recent days, encryption techniques are the important thing to secure our personal communications and
messages. Encryption techniques are promptly increased by the increasing usage of communication networks
and evaluation of the internet. Sharing an information from one end to another end over an unsecured channel
opens a door for hacking or attacking the information. In order to reduce this and to provide better security,
encryption techniques are playing a vital role. Caesar cipher is one among the ancient and a simple encryption
technique, which is also known as substitution cipher that means a cipher which substitutes one alphabet to
another. But this method is too easy to break the letters. Atbash cipher is one of the monoalphabetic cipher, here
the encryption is done by using the Hebrew alphabet, that is it will be encrypted by mapping every alphabet to its
reverse order. In this paper, we implement a new encryption technique that will combine Caesar Cipher with
Atbash Cipher (CCAC) in order to provide more security than the original Caesar cipher and Atbash Cipher and
resist hackers.
