Analysis and Improvement of an Efficient Certificate-Based Signature Scheme
摘要
Abstract
From the study of an efficient certificate-based signature we find that the first adversaries can attack the scheme easily.As a consequence, we propose an improved scheme on the basis of original scheme , and prove that the scheme is existen-tially unforgeable against adaptive chosen message and identity attacks under random oracle model based on the inverse Diffie-Hell-man Problem and Compute Diffie-Hellman assumption.In this paper we also analyze the efficiency of the scheme , compare with the existing schemes, find that this scheme is effective.关键词
