ASCII Based Even-Odd Cryptography With Gray Code and Image Steganography: A Dimension in Data Security
Source: Khulna University
The message is the composition of some character. Every character of the message can be represented as an ASCII value, which is either even or odd. Depending on this evenness or oddness, the character is encrypted differently. This paper describes how such an even-odd encryption based on ASCII value is applied and how encrypted message converting by using Gray code and embedding with picture can secured the message and thus makes cryptanalyst's job difficult.
