Modern Enhancement for Cryptography using Caesar Cipher Algorithm

The Caesar Cipher set of rules for cryptography is one of the oldest algorithms. Now a great deal newer algorithms have arrived which might be plenty greater at ease, however in terms of velocity of execution Caesar cipher set of rules remains the quickest as a result of its simplicity. However the algorithm is extraordinarily smooth to crack. This is because on this set of rules each individual of a message is usually replaced by means of the equal constant individual that has been predetermined. To enhance the algorithm and enhance it is safety feature, some adjustments may be brought. This paper proposes an enhancement to the present algorithm by using making use first of a easy Diffie-Hellman key trade scenario to achieve a mystery key and later using simple arithmetic to make sure the encryption of statistics is tons extra safer. as soon as a personal shared key is obtained through utilising the Diffie-Hellman method, the secret is concern to the mod operation with 26 to gain a price much less than or identical to 26, then the contemporary person is taken and to this the key value acquired is brought to achieve a new character. For any individual within the x function the secret is genuinely first accelerated with x after which mod is executed to obtain the encrypted man or woman. So 2d man or woman of the message is expanded with 2, 1/3 person with three and so on. This enhances the safety and also does now not boom the time of execution through a big margin.
