OceanStore is a utility infrastructure designedto span the globe and provide continuous access to persistent information. Since this infrastructure is comprised of untrusted servers, data is protected through redundancy and cryptographic techniques. To improve performance, data is allowedtobe cached anywhere, anytime. Finally, monitoring of usage patterns allows adaptation to regional outages and denial of service attacks; monitoring also enhances performancethrough pro-active movement of data. A prototype implementation is currently under development.
