Improved Method to Increase AES System Speed

Increase the speed of the AES system in communicates the data secretly using AES Algorithm i.e. we first send the data (plain text) and the key which is of 128/256 bit into the encryption process .The output of this process will be cipher text. This cipher text is then fed into the decryption process and then the data (plain text) is get as output. The main aim is that since we add the key and shuffle the data it is very hard for the unknown person to find out the original data. Since for each key there will be a change in the cipher text and so the person has to know the key in order to find out the original data.
