Title

A Fast And Secure Encryption And Decryption Algorithm For Data Transmission And Reception

Author

Pamarthy Ashok Chakravarthy, Ravi Krishna Penukuduru

 To solve the problem of message communication over an insecure channel we have several encryption and decryption standards such as DES (Data Encryption Standard), AES (Advanced Encryption Standard) and EES (Escrowed Encryption Standard) which were widely used in now a days. Due to advanced hacking technics in computers and embedded systems these standards seem not to be as secure and fast. We proposed in this paper a fast and secure encryption algorithm using substitution mapping, translation and transposing operations. We propose a technique that the encryption and decryption procedures are much simpler, and consequently, much faster and the security level is much higher. The proposed algorithm is compared with popular encryption and decryption algorithms and is implemented on ARM7 (LPC2148) controller.
