This paper describes a compact 32 bit architecture developed for the Rijndael cyphering/decyphering system. The implementation complies with the NIST Advanced Encryption standard. The design processes 128-bit block data with 128-bit key. For an area-saving implementation, the field inversion block and the key scheduling circuits are shared by both the encryption and decryption process.
