This document contains the Intellectual Property Statement and the technical description of the MQQ-SIG - a new public key digital signature scheme. The complete scientific publication covering the design rationale and the security analysis will be given in a separate publication. MQQ-SIG consists of $n - \frac{n}{4}$ quadratic polynomials with $n$ Boolean variables where $n=160$, $192$, $224$ or $256$.

Note: Change in the algorithm for generation of non-singular matrices in order to speed-up the slow key generation process. Updated measurements.
