Abstract: 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 $256$.

Category / Keywords: Public Key Cryptosystems, Fast signature generation, Multivariate Quadratic Polynomials, Quasigroup String Transformations, Multivariate Quadratic Quasigroup
