We first analyze the security of a short signature scheme without random oracles called ZCSM scheme and point out that it cannot support unforgeable under the chosen message and ...

The standard digital signature scheme can be easily subject to key exposure problem In order to overcome this problem; a feasible and effective approach is employed by key-evolving...
— In this paper, we propose a new pairing-based proxy signature. Most remarkable point in our proposal is that our scheme realizes short signature. More concretely, the explicit ...
We present a new undeniable signature scheme which is based on the computation of characters. Our signature scheme offers the advantage of having an arbitrarily short signature. I...
Abstract. This paper shows some efficient and provably-secure convertible undeniable signature schemes (with both selective conversion and all conversion), in the standard model an...
