Real-Time, Byzantine-Tolerant Information Dissemination in Unreliable and Untrustworthy Distributed Systems

In unreliable and untrustworthy systems, information dissemination may suffer network failures and attacks from Byzantine nodes which are controlled by traitors or adversaries, and can perform destructive behaviors. Typically, Byzantine nodes together or individually "swallow" messages, or fake disseminated information. In this paper, we present an authentication-free, gossip-based real-time information dissemination mechanism called RT-LASIRC, in which "healthy" nodes utilize Byzantine features to defend against Byzantine attacks. We show that RT-LASIRC is robust against blackhole and message-faking attacks. Our experimental studies verify RT-LASIRC\´s effectiveness.
