Abstract

We propose a configurable AES processor for extended-security communication. The proposed architecture can provide up to 2 19 different AES block cipher schemes within a reasonable hardware cost. Data can he encrypted not only with secret keys and initial vectors, but also by different block ciphers during the communication. A novel on-the-fly key expansion design is also proposed for.128-, 192-, and 256-bit keys. Our unified hardware can run both the original AES algorithm and the extended AES algorithm. The proposed processor design has been fabricated by a 0.25μm CMOS process, with a silicon area of 6.93mm 2-about 200.5K equivalent gates. Under a 66MHz clock, the throughput rate for both the ECB and CBC operation modes are S44.8Mbps, 704Mbps, and 603.4Mbps for 128-bit, 192-bit, and 256-bit keys, respectively.
