Most existing work which merges Fault Tolerance into Security concentrates on using fault tolerance as a means of bolstering a server's resilience to external attack. The most notable of this work is carried out by Reiter on Rampart.
Our talk aims to discuss two main themes:
Firstly, that we can use the principles that underpin fault tolerance to broaden its use in security, and not only rely upon using existing mechanisms poached cleanly from fault tolerance.
Secondly, we wish to demonstrate that by using such principles we can actually use fault tolerance to reduce reliances in a secure system, and move away from the Trusted Computing Base model for distributed secure computing.
