Abstract
This dissertation studies the effects on system design when including fault tolerance design principles within security services. We start by looking at the changes made to the trust model within protocol design, and how moving away from trusted server design principles affects the structure of the protocol. Taking the primary results from this work, we move on to study how control in protocol execution can be used to increase assurances in the actions of legitimate participants. We study some examples, defining two new classes of attack, and note that by increasing client control in areas of protocol execution, it is possible to overcome certain vulnerabilities. We then look at different models in fault tolerance, and how their adoption into a secure environment can change the design principles and assumptions made when applying the models. We next look at the application of timing checks in protocols. There are some classes of timing attack that are difficult to thwart using existing techniques,
