Ultra-Compact Advanced Encryption Standard (AES, FIPS-197) Core

The AES core implements Rijndael cipher encoding and decoding in compliance with the NIST Advanced Encryption Standard. It processes 128-bit data blocks with 128-bit key (a 256-bit key version is available).

Basic core is designed only for encryption and is the smallest available on the market (less than 3,000 gates). Enhanced versions are available that support encryption and decryption for various NIST cipher modes (ECB,CBC, OFB, CFB, CTR), as well as different datapath widths for size/performance tradeoff. The core includes the key expansion logic.

The design is fully synchronous and available in both source and netlist form.

Optional data integrity and differential power attack resistance features.
