Abstract(in English) | Debris-Alazard, Sendrier, and Tillich proposed SURF in 2017, which is an efficient code-based signature scheme. However, it was broken because the hardness of the plain (U,U+V)-code problem over $¥mathbb{F}_2$ which the security of SURF is based on does not hold. Then Debris-Alazard~et~al.~proposed Wave, a successor of SURF in 2019. The security of Wave is based on the normalized generalized (U,U+V)-code problem over $¥mathbb{F}_3$ and has not attacked yet. In this work, we utilize the notion of Gramians and analyze the problem of SURF more simply. Furthermore, in some special cases, we analyze the problem of Wave with Gramians. |
