A Generic Scheme Based on Trapdoor One-Way Permutations with Signatures as Short as Possible
We answer the open question of the possibility of building a digital signature scheme with proven security based on the one-wayness of a trapdoor permutation and with signatures as...

Directed Transitive Signature Scheme
In 2002, Micali and Rivest raised an open problem as to whether directed transitive signatures exist or not. In 2003, Hohenberger formalized the necessary mathematical criteria for...

Proposal of a Signature Scheme Based on STS Trapdoor
A New digital signature scheme based on Stepwise Triangular Scheme (STS) is proposed. The proposed trapdoor has resolved the vulnerability of STS and secure against both Gr¨obner ...

On the Security of the Winternitz One-Time Signature Scheme
Abstract. 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 ...

Code-based Ring Signature Scheme
McEliece is one of the oldest known public key cryptosystems, however it was not quite as successful as RSA. One main reason is that it is widely believed that code-based cryptosy...
