| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | A problem of solving a system of multivariate quadratic polynomials over a finite field, which is called an MQ problem, is a promising problem in cryptography. However, the security of the existing multivariate public-key schemes relies not only on the MQ problem but also on an Isomorphism of Polynomials (IP) problem. In this talk, we introduce our paper ``Public-Key Identification Schemes Based on Multivariate Quadratic Polynomials'' which is presented at CRYPTO 2011. The paper proposes public-key identification schemes based on the MQ problem which do not rely on the IP problem. For a practical parameter choice, the efficiency of our schemes is highly comparable to that of identification schemes based on another problem including Permuted Kernels, Syndrome Decoding, Constrained Linear Equations, and Permuted Perceptrons. |
