Abstract: Internet play a vital role for sharing information online but this mode is dangerous for data hacking and cracking by the unauthorized person. Information security is an important requirement of today world due to increasing use of internet. The privacy of information can be achieved through cryptography by applying the encryption process on the plain text being transmitted over network. Encryption is the process of converting the original text into cipher text so that only intended receiver of the message can read it. In this paper we proposed a new ASCII code based substitution technique for text encryption which is more secure than Caesar Cipher substitution technique and proposed technique is implemented in java. In the proposed technique we used the ASCII value of the character and the position of the alphabet for encrypting the plain text.
Keywords: Cryptography, Substitution, Encryption, Decryption, ASCII Value.
