Self-stabilizing byzantine asynchronous unison

Abstract : We explore asynchronous unison in the presence of systemic transient and permanent Byzantine faults in shared memory. We observe that the problem is not solvable under a less than strongly fair scheduler or for system topologies with maximum node degree greater than two. We present then a self-stabilizing Byzantine-tolerant solution to asynchronous unison for chain and ring topologies under the central strongly fair daemon. Our algorithm has minimum possible containment radius and optimal stabilization time.
