SoC Implementation of AES 128 bit Algorithm for IEEE 802.16e Mobile WiMax Standards

Abstract

Wireless Technology plays a very vital role in data transmission process. The most widely used wireless technology standard is IEEE 802.16. Especially the basic standards like Zig-be, Li-Fi, Bluetooth and Wi-Max be the most widely used for connecting point to multipoint networks wirelessly in a secured environment. Security is the main issue of any transmission system in today's world. Many security algorithms were proposed for the MAC layer in Wi-Max but most commonly used is AES (Advanced Encryption Standard) algorithm. In this paper 128-bit AES algorithm is implemented in CTR mode. CTR mode is preferred compared to other modes because it avoids data dependency both in encryption and decryption process. All the Blocks were designed using Verilog HDL, simulated using ncvlog simulator, synthesized in cadence- RTL Complier and finally implemented in Soc Encounter using GPDK 45nm technology libraries.
