| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Evaluating non-linear multivariate polynomial systems over finite fields is an important subroutine for QUAD stream cipher. The security of QUAD definitely becomes lower if a larger field is used instead of $GF(2)$ given the same number of bits in the key. However, we still would like to use larger fields because QUAD tends to run faster at the same level of security if a larger field is used. In this paper, we substitute Optimal Extension Fields (OEF) for $text{GF}({2}^{32})$ to a finite field of multivariate quadratic polynomials. QUAD over $text{GF}({2}^{32}-5)$ with 64 polynomials in 32 variables is 9 times faster than over $text{GF}({2}^{32})$ on GPU. |
