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.
