Abstract


The most challenging area in today’s era is security over the network because now days all the industrialists, corporate sectors shares their precious information through internet. Researchers have designed various encryption techniques like Caesar cipher, play fair cipher, hill cipher, one time pad cipher, alpine cipher etc. to secure the information. Caesar cipher gets easily affected from any brute force attacker. By considering the cons of the existing Caesar cipher, a new technique is proposed in this paper which enhances its strength and puts stronger impact on the cipher text result which makes difficulty for a brute force attacker to determine the original plaintext back.
