Costs of Security in the PFS File System

Walsh, Kevin; Schneider, Fred
Various principles have been proposed for the design of trustworthy systems. But there is little data about their impact on system performance. A filesystem that pervasively instantiates a number of well-known security principles was implemented and the performance impact of various design choices was analyzed. The overall performance of this filesystem was also compared to a Linux filesystem that largely ignores the security principles.
