An Efficient Design of Security Accelerator for IEEE 802.15.4 Wireless Senor Networks

In this paper, we provide a low cost AES core for ZigBee devices which accelerates the computation of AES algorithms. Also, by embedding the AES core, we present an efficient architecture of security accelerator satisfying the IEEE 802.15.4 specifications. In our experiments, we observed that the AES core and the security accelerator use fewer logic gates and consume lower power than other architectures based on block-wide and folded ones.
