The encryption standards such as Data Encryption Standard (DES), Advanced Encryption Standard (AES) and Escrowed Encryption Standard (EES) are widely used to solve the problem of communication over an insecure channel. With advanced technologies in computer hardware and software, these standards seem not to be as secure and fast as one would like. In this paper, the authors propose a fast and secure encryption algorithm using substitution mapping, translation and transposing operations. Like one's compliment methodology the proposed symmetric encryption technique has two advantages over traditional schemes.
