In this thesis, we propose an efficient Field Programmable Gate Arrays (FPGA) to implement Advanced Encryption Standard (AES) algorithm. The proposed design is based on the pipelined architecture that unrolls the 10 AES rounds to ensure the higher throughput, easer hardware architecture and optimized frequency. This implementation includes encryptor and decryptor which fit the most embedded applications, such as wireless devices, smart card and so on. We use Verilog, Xilinx ISE and ModelSim simulator to implement the chip design.
