A Comprehensive Reference Architecture for Trustworthy Long-Term Archiving of Sensitive Data

It is well known that the suitability of many cryptographic algorithms decreases with time. Hence, it is a challenging task to maintain the integrity, authenticity, confidentiality and availability of sensitive data over very long periods of time. A scalable approach to preserve the integrity and authenticity of archived data has been standardized in (T. Gondrom et al., August 2007). The confidentiality and availability of data can be supported using secret sharing techniques according to (A. Shamir, 1979). This paper introduces a reference architecture for trustworthy long-term archiving of sensitive data based on the combination of these approaches.
