Title: Regarding Timeliness In The Context Of Fair Exchange
Author: Piva F.R.
Monteiro J.R.M.
Dahab R.
Abstract: In this paper we discuss the often overlooked timeliness property of fair exchange protocols. We gather different available definitions of this property, and propose a new and stronger interpretation for timeliness in the context of security protocols. We discuss common timeliness-related pitfalls in fair exchange protocol design, and show a particular timeliness attack effective in several optimistic protocols proposed in the literature. Finally, we provide guidelines that may help to avoid common mistakes in protocol design, and propose our own protocol that ensures both fairness and timeliness. © 2009 ESRGroups France.
