Blockchain-Based Dynamic Key Management for Heterogeneous Intelligent Transportation Systems
TL;DR: Extensive simulations and analysis show the effectiveness and efficiency of the proposed framework, in which the blockchain structure performs better in term of key transfer time than the structure with a central manager, while the dynamic scheme allows SMs to flexibly fit various traffic levels.
Journal ArticleDOI
Security and Privacy in Location-Based Services for Vehicular and Mobile Communications: An Overview, Challenges, and Countermeasures
Philip Asuquo,Haitham Cruickshank,Jeremy Morley,Chibueze P. Anyigor Ogah,Ao Lei,Waleed Hathal,Shihan Bao,Zhili Sun +7 more
TL;DR: This paper covers privacy enhancing technologies and cryptographic approaches that provide location privacy in vehicular and mobile networks that are proposed in literature and open research areas are identified.
Journal ArticleDOI
A Distributed Trust Management Scheme for Data Forwarding in Satellite DTN Emergency Communications
TL;DR: A decentralized trust management scheme (DTMS) to filter out malicious nodes in DTNs and shows that DTMS can effectively deal with malicious behaviors inDTNs including trust related attacks.
Journal ArticleDOI
A Secure Key Management Scheme for Heterogeneous Secure Vehicular Communication Systems
TL;DR: The GKM results demonstrate that probability-based BR reduces rekeying cost compared to the benchmark scheme, while the blockchain decreases the time cost of key transmission over heterogeneous networks.
Proceedings ArticleDOI
Privacy-Enhanced Group Communication for Vehicular Delay Tolerant Networks
Chibueze P. Anyigor Ogah,Haitham Cruickshank,Zhili Sun,Ganesh Chandrasekaran,Yue Cao,Philip Asuquo,Masoud Al Tawqi +6 more
TL;DR: An improved privacy scheme based on group communication scheme in VDTNs is reported on and it is reported that this scheme has considerable improvement compared to other similar schemes described in literature.
