A New Variant of the Winternitz One Time Signature Scheme Based on Graded Encoding Schemes
graded encoding schemes multi-linear maps GDL problem
2019/2/28
The Winternitz one-time signature (WOTS) scheme, which can be described using a certain number of so-called ``function chains", plays an important role in the design of both stateless and stateful man...
On the Security of the Winternitz One-Time Signature Scheme
public-key cryptography / Hash-based signatures post-quantum signatures pseudorandom functions security reductions
2012/3/28
We show that the Winternitz one-time signature scheme is existentially unforgeable under adaptive chosen message attacks when instantiated with a family of pseudo random functions. Compared to previou...
A new one-time signature scheme from syndrome decoding
one-time signature scheme syndrome decoding
2010/1/18
We describe a one-time signature scheme based on the hardness
of the syndrome decoding problem, and prove it secure in the random
oracle model. Our proposal can be instantiated on general linear
