Overview: This paper from Hewlett-Packard has introduced novel uses of cryptographic primitives applied to the problem of secure storage in the presence of untrusted servers and a desire for owner managed key distribution. Eliminating almost all requirements for server trust (one still requires servers not to destroy data although one can detect if they do) and keeping key distribution (and therefore access control) in the hands of individual data owners provides a basis for a secure storage system that can protect and share data at very large scales and across trust boundaries.
