Cryptanalysis and Improvement of Certificateless AggregateSignature Scheme
摘要
Abstract
Aggregate signature technology has a good application in resource-constrained scenarios and is a hotspot in digital signature research.The security of the certificateless aggregate signature scheme proposed by Du et al is analyzed,and we find that the scheme can not resist the forgery attack.Based on the Du scheme,an improved scheme of certificateless aggregate signature is proposed.Under the assumption of stochastic prediction model and Computational Diffie-Hellman (CDH) problem,the unforgeability of the improved scheme is proved,and the efficiency analysis shows that the improved scheme is safer and more efficient.关键词
