INTEGRATED INTERNET MEASUREMENT MODEL

A software defined radio (SDR) is a radio transmitter/receiver that uses reconfigurable hardware and software for encoding/decoding, modulation/demodulation, and encrypting/decrypting. This allows much more power and flexibility when de signing any radio system. The AES algorithm is a block cipher that can encrypt and decrypt digital information. The AES algorithm is capable of using cryptographic keys of 128, 192, and 256 bits. The Rijndael cipher has been selected as the official Advanced Encryption Standard (AES) as it i s well suited for reconfigurable hardware. The Advanced Encryption Standard can be programmed in software or built with hardware. However Field Programmable Gate Arrays (FPGAs) offer a more customized solution.
