Abstract

Self-stabilizing protocols can tolerate any type and any number of transient faults. However, in general, self-stabilizing protocols provide no guarantee about their behavior against permanent faults. This paper proposes a self-stabilizing link-coloring protocol resilient to (permanent) Byzantine faults in arbitrary networks. The protocol assumes the central daemon, and uses 2Δ−1 colors where Δ is the maximum degree in the network. This protocol guarantees that any link (u,v) between non faulty processes u and v is assigned a color within 2Δ+2 rounds and its color remains unchanged thereafter. Our protocol is Byzantine insensitive in the sense that the subsystem of correct processes remains operating properly in spite of unbounded Byzantine faults.
