On the security of long-lived archiving systems based on the evidence record syntax

Abstract

The amount of security critical data that is only available in digital form is increasing constantly. The Evidence Record Syntax Specification (ERS) achieves very efficiently important security goals: integrity, authenticity, datedness, and non-repudiation. This paper supports the trustworthiness of ERS by proving ERS secure. This is done in a model presented by Canetti et al. that these authors used to establish the long-term security of the Content Integrity Service (CIS). CIS achieves the same goals as ERS but is much less efficient. We also discuss the model of Canetti et al. and propose new directions of research.
