无证书聚合签名方案的攻击与改进
Attack and improvement of a certificateless aggregate signature scheme
摘要
Abstract
Aggregate signature becomes a hot topic in the digital signature technology researches because of its wide application in the Internet of Things.Ming et al.(201 4)proposed an efficient certificateless aggregate signature scheme.But Zhang et al.(201 5 )showed the scheme is not secure against a Type II adversary,and then they proposed an improvement of Ming's scheme.However,it is pointed out that the improved scheme is still insecure against a Type II adversary by giving specific attacks.Then,based on Ming's scheme,a new certificateless aggregate signature scheme is constructed.The new scheme is prov-ably-secure in the random oracle model and the length of aggregate signature is constant so that it is suit-able for the Internet of Things.关键词
