BSMR: Byzantine-Resilient Secure Multicast Routing in Multi-hop Wireless Networks

ABSTRACT

Multi-hop wireless networks rely on node cooperation to provide unicast and multicast services. The multi-hop communication offers increased coverage for such services, but also makes them more vulnerable to insider (or Byzantine) attacks coming Continue reading

A Network-Aware Distributed Membership Protocol for Collaborative Defense

ABSTRACT

To counteract current trends in network malware, distributed solutions have been developed that harness the power of collaborative end-host sensors. While these systems greatly increase the ability to defend against attack, this comes at the cost Continue reading
