内容記述 | The unbalanced oil and vinegar signature scheme (UOV) is a signature scheme whose public key is a set of multivariate quadratic forms over a finite\nfield. This -signature scheme has been considered to be secure and efficient enough under suitable parameter selections. However, the key size of UOV is\nrelatively large and then reducing the key size of UOV is an important issue. Recently in Inscrypt 2015, a new variant of UOV called Cubic UOV was proposed,\nand in ICISC 2016, two variants of Cubic UOV called CSSv and SVSv were proposed. It has been claimed that these variants were more efficient than\nthe original UOV and were secure enough. However, the security analyses of these schemes were not enough and they can be broken easily. In the present\npaper, we describe the weaknesses of these schemes. | |||||||
