This paper proposes a new ID-based proxy signature scheme based on the bilinear pairings. The number of paring operation involved in the verification procedure of our scheme is onl...
Abstract. In this article, it is discussed how to construct a compression function with 2n-bit output using a component function with n-bit output. The component function is either...
We present a technique for delegating a short lattice basis that has the advantage of keeping the lattice dimension unchanged upon delegation. Building on this result, we construct...
The length-based approach is a heuristic for solving randomly generated equations in groups which possess a reasonably behaved length function. We describe several improvements of ...
We present a new short signature scheme based on a variant of the Boneh-Boyen's short signatures schemes. Our short signature scheme is secure without requiring the random or...
