Web4 dec. 2015 · Here ends today’s blogpost! There are many more one-time signature schemes, if you are interested here’s a list, some of them are even more than one-time signatures because they can be used a few times. So we can call them few-times signatures schemes (FTS): 1994, The Bleichenbacher-Maurer OTS. 2001, The BiBa OTS. WebHash-based signature algorithms are comprised of two schemes, an underlying signing scheme and an extension algorithm. The former algorithm de nes the main signing procedure where a key pair can be used to sign one (Lamport [19], Winternitz one time signature scheme (WOTS), WOTS++ [8,14]) or a few
