In any wireless communication, security is crucial during data transmission. The encryption and decryption of data is the major challenge faced in the wireless communication for security of the data. These algorithms are used to ensure the security in the transmission channels. Similarly hardware utilization and power consumption are other major things to be considered since most of the mobile terminals are battery operated. In this paper, the authors use the Advanced Encryption Standard (AES) which works on a 128 bit data encrypting it with 128, 192 or 256 bits of keys for ensuring security.
