A Comprehensive Reference Architecture for Re-encryption based Archival Systems with Insurability Services

It is observed and well known that the most challenging task is to maintain availability, reliability and security of archival over a long period of time. A scalable and dynamic approach like periodical re-encryption is used to preserve these crucial features. Ensuring the retained archival in a verifiable way is a special issue due to the effect of re-encryption. The insurance to an archival is an important mechanism to quantify the value of retained document. This paper proposes a reference architecture for re-encryption based archival system with insurability services by combining the different requirements of archival users.
