Let V be a 3-dimensional vector space over a finite field. We show that any irreducible subgroup of GL(V ) that arises as the automorphism group of an regular polytope preserves a...
We consider point-line geometries having three points on every line, having three lines through every point (bislim geometries), and containing triangles. We classify such geometr...
Group signatures is a powerful primitive with many practical applications, allowing a group of parties to share a signature functionality, while protecting the anonymity of the si...
