| Abstract(in English) | The Blum-Kalai-Wasserman (BKW) algorithm is widely known as an algorithm for solving the Learning Parity with Noise (LPN) problem. The BKW algorithm includes the following process at a certain stage: the input set of vectors is divided into several sets according to certain features, a specific vector is selected for each set, and a linear transformation is performed using this vector. In the existing BKW algorithm, the specific vector is selected according to a uniform distribution. Our research focuses on the possibility that the method of selecting this particular vector may affect the accuracy of the solution of the LPN problem output by the BKW algorithm. This paper proposes a new method for selecting the specific vectors and evaluates the accuracy of the outputs of the modified BKW algorithm which employs the new method through machine experiments. Compared with the existing BKW algorithm, we can confirm the improvement of accuracy by the proposed method. |
