Description

Simple AES (Rijndael) IP Core. I have tried to balance this implementation and to trade off size and performance. The goal was to be able to fit in to a low cost Xilinx Spartan series FPGA and still be as fast as possible. As one can see from the implementation results below, this goal has been achieved ! Other Implementations of this standard with different key sizes (192 & 256 bit) and performance attributes (like a fully pipelined ultra-high-speed version) are commercially available from ASICS.ws. Even though no official testing has been performed we believe that this core is fully complies to FIPS-197 (pdf). For more information see the core documentation.

Features

 

  • 16 byte block size
  • 16 byte key size
  • separate cipher (encrypt) block
  • separate inverted cipher (decrypt) block
  • incorporated key expansion module
  • written in verilog

Status

- Nov 12, 2002 Found a bunch of test vectors on the NIST site, added them today to the testbench. Added missing timescale.v file.
- I could use some "official" testvectors. If you know were to get them or have any, please contact the author.
- This core is done. Initial Release: Nov. 9, 2002
