A Topological Approach to Secure Message Dissemination in Vehicular Networks. (arXiv:1803.08221v1 [cs.IT])
来源于:arXiv
Secure message dissemination is an important issue in vehicular networks,
especially considering the vulnerability of vehicle to vehicle message
dissemination to malicious attacks. Traditional security mechanisms, largely
based on message encryption and key management, can only guarantee secure
message exchanges between known source and destination pairs. In vehicular
networks however, every vehicle may learn its surrounding environment and
contributes as a source, while in the meantime act as a destination or a relay
of information from other vehicles, message exchanges often occur between
"stranger" vehicles. For secure message dissemination in vehicular networks
against insider attackers, who may tamper the content of the disseminated
messages, ensuring the consistency and integrity of the transmitted messages
becomes a major concern that traditional message encryption and key management
based approaches fall short to provide. In this paper, by incorporating the
underlying network t 查看全文>>
