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
