摘要：In this proposed work, implemented a cryptographic system for symmetric encryption and hamming code for error detection and correction. Symmetric key is using same duplicate data i.e. key data for both encryption and decryption. In this encryption and decryption process hamming code which is used to check the one bit error if any. Encrypting a message can be done by supplying a message along with the key while the process of decryption can be done by passing the key along with the resultant output in order to obtain the original message. For this process AES algorithm was adopted. The original 8-bit data is 1�s complemented and it will be swapped based on the select lines and swapped data is XOR�ed with the original data finally the encrypted data will be transmitted. Encrypted data is the combination of both swapped data and encrypted data i.e.16-bit data. To get original message data the Swapped data is XOR�ed with the encrypted data which is decrypted data.
