PASIS: A Distributed Framework for Perpetually Available and Secure Information Systems
Abstract
This document reports on the results of the DARPA project entitled "PASIS: A Distributed Framework for Perpetually Available and Secure Information Systems" funded by Air Force award F30602-99-2-0539. The PASIS project developed architectures and technologies for information storage systems that can survive attacks and failures both at the small - and the large - scale. Specifically PASIS storage systems are designed to be: Perpetually Available: Information should always be available even when some system components are down or unavailable. Perpetually Secure: Information integrity and confidentiality policies should always be enforced even when some system components are compromised. Graceful in Degradation: Information access functionality and performance should degrade gracefully as system components fail. Achieving these objectives in practice also requires that performance and usability features of conventional (non-survivability) storage systems be maintained. Therefore the PASIS project also developed trade-off management programming and administrative tools for PASIS systems.
