Hardware Security Appliances for Trust

This paper looks at the trust relationships that exist within an outsourcing scenario finding that whilst some of the trust relationships are clear other implicit trust relationships need exposing. These implicit trust relationships are often a result of information supplied for the main explicit task for which an entity is being trusted. The use of hardware security appliance based services is proposed allowing trust to be dissipated over multiple parties whilst retaining efficient execution. Such an approach helps mitigate these implicit trust relationships by increasing the control and transparency given to the trustor.
