FlexArchive: A Re-Configurable Distributed Archival Store Based on Secret Sharing

Modern storage systems are often faced with complex tradeoffs between the confidentiality, availability, and performance they offer their users. Secret sharing is a data encoding technique that provides information-theoretically provable guarantees on confidentiality unlike conventional encryption. Additionally, secret sharing provides quantifiable guarantees on the availability of the encoded data. The authors argue that these properties make secret sharing-based encoding of data particularly suitable for the design of increasingly popular and important distributed archival data stores. These guarantees, however, come at the cost of increased resource consumption during reads/writes.
