Matching key recovery mechanisms to business requirements

Abstract

This paper addresses the business needs for key recovery as a counter-measure to the threat of losing potentially valuable information. Several requirements essential for a sound key recovery mechanism are described, and the applicability of two main classes of existing key recovery schemes to a corporate environment is examined. Different requirements are indentified for key recovery mechanisms for communicated and archived data, and a further study is made of the applicability of existing mechanisms to these two cases.
