Mobile Ad hoc NETworks (MANETs) are collections of wireless mobile devices with restricted broadcast range and resources, and no fixed infrastructure. Communication is achieved by relaying data along appropriate routes that are dynamically discovered and maintained through collaboration between the nodes. Discovery of such routes is a major task, both from efficiency and from a security point of view. Recently, a security model tailored to the specific requirements of MANETs was introduced by Acs, Buttyan, and Vajda. Among the novel characteristics of this security model is that it promises security guarantees under concurrent executions, a feature of crucial practical implication for this type of distributed computation.
