We present a new quasigroup based block encryption system with and without cipher-block-chaining. We compare its performance against Advanced Encryption Standard-256 (AES256) bit algorithm using the NIST statistical test suite (NIST-STS) that tests for randomness of a sequence. Since it is well known that a good encryption algorithm must destroy any statistical properties of the input sequence and produce an output close to a true random sequence, the NIST-STS suite results provide a good test bench. In almost all tests from the suite the proposed algorithm performs better than AES256.

We present an efficient hardware implementation of a quasigroup block cipher system. Power and resource comparisons are done with AES and we show that the proposed quasigroup system provides an inexpensive alternative for SCADA networks and other low powered, resource constrained devices.
