Motivated by the above line of research, we focus on effi- cient signature schemes with tight security reductions, and improve the efficiency (both in terms of ...
We present a modification of their scheme in which signing is 33% more efficient and signatures are 75% shorter; the security of this scheme is tightly related ...
Nov 6, 2019 · We now propose the general framework that tightens the security of FDH signatures using properties of the trapdoor samplable relations. The ...
Nov 26, 2019 · In this paper, we take a step further to propose a general framework that is able to achieve backward compatibility while maintaining the tight ...
Abstract. We propose and analyze two efficient signature schemes whose security is tightly related to the Diffie-Hellman problems in the random oracle model ...
