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...
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...
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 ...
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 ...

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...
