【Abstract】Given the ubiquitous nature of wireless networks in today's society, protecting users' information and identity during handover authentication is paramount. Mobile network operators hope to implement a more flexible and fine-grained authentication to provide better and safer services. In this paper, we propose a new multi-attribute authority attribute-based signature (MA-ABS) scheme that has a constantsize signature. More specifically, we propose an anonymous handover authentication protocol that uses MA-ABS and consortium blockchain. This new protocol not only has fine-grained access control, but it protects the user's privacy and ensures an efficient and private handover. (C) 2021 Elsevier Inc. All rights reserved.
