In earlier work, we described a “pathological” example of a signature scheme that is secure in the Random Oracle Model, but for which no secure implementation exists. For that...

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 ...
