The advent of multicore technologies is set to significantly increase the average compute power per machine. Effective and efficient exploitation of this power poses unprecedented challenges and opportunities. The Pleiades system, currently under development in UCF, CSU and UCC [1], proposes the construction of a distributed, heterogeneous, and secure marketplace for trading and administer these resources whose owners sign up to various quality of service (QoS) contracts, in return for financial and in-kind payment. This paper presents a very important part of the Pleiades system: addressing the role of Trust Management (TM) in the generation and enforcement of these contracts. The approach taken significantly reduces the overhead that is traditionally assumed with cryptographic solutions, by the dynamic and a priory creation of a secure environment in which these expensive checks associated with cryptographic solutions, are not required.
