An Infrastructure for Long-Term Archiving of Authenticated and Sensitive Electronic Documents

摘要

Secure archiving of authenticated and sensitive documents is becoming a necessity due to the dematerialization of paper based documents and processes. Huhnlein et al. combined the Open Archival Information System (OAIS) Reference Model, Evidence Record Syntax (ERS) with Secret Sharing and proposed the Comprehensive Reference Architecture for Trustworthy Long-Term Archiving of Sensitive Data. However, their proposal requires the secret reconstruction and redistribution whenever there are changes in the structure of the servers. In addition, there are some unhandled problems (e.g. compromise of the servers) and open issues (e.g. specification of a protocol) in their proposal. In this article we propose the use of a modified version of Gupta's and Gopinath's protocol G_(its)~2 Verifiable Secret Redistribution (VSR), among other mechanisms, in order to improve the reference architecture, making it suitable for long-term archiving.
