Multi-Step Simulation Approach Toward Secure Fault Tolerant System Evaluation

摘要

As new techniques of fault tolerance and security emerge, so does the need for suitable tools to evaluate them. This paper presents a multi-step, simulation-based performance evaluation methodology for secure fault tolerant systems. A divide-and-conquer approach is used to model the entire secure system in a way that allows the use of different analytical tools at different levels of granularity. This evaluation procedure tries to strike a balance between the efficiency, effort, cost and accuracy of a system's performance analysis. This approach is demonstrated in a step-by-step manner by analyzing the performance of a secure and fault tolerant system using a JAVA implementation in conjunction with the ARENA simulation.
