<p>As society increasingly relies on digitally stored and accessed information, supporting the availability, integrity, and confidentiality of this information is crucial. Systems need to help users securely store critical information, ensuring that it persists, is continuously accessible, cannot be destroyed, and is kept confidential. The authors show why they believe a survivable storage system would provide these guarantees, despite malicious compromises of storage node subsets.</p> <p>This article describes the PASIS architecture, which combines decentralized storage system technologies, data redundancy and encoding, and dynamic self-maintenance to create survivable information storage.</p> <p>The authors explain how the PASIS architecture flexibly and efficiently combines technologies for constructing in-formation storage systems whose availability, confidentiality, and integrity policies can survive component failures and malicious attacks.</p>
