This work present an optimized pipelined hardware implementation of the advanced encryption standard (AES) with key lengths of 128, 192 and 256 bits on an altera stratix III-EP3SL150F1152 field programmable gate array (FPGA). Starting from an architecture dedicated to 256-bit key operations, a series of optimization are performed to allow the handling of 128-bit and 192-bit keys, using one core, rather than three separate cores. The various operations required for the AES algorithm are thus analyzed from a hardware implementation perspective. The system throughput is also enhanced through the simultaneous calculations of operations. In the timing report, the system frequency reaches a maximum of 332 MHz producing a maximum throughput of 42.48 Gbps with a latency ranges from 21 to 29 clk cycles depending on the selected operation. The design was tested on a terasic DE3-150 development board at 100 MHZ, and operated with the Altera-NiosII CPU environment
