Report of the NIST Workshop on Key Escrow Encryption. Held in Gaithersburg, Maryland on June 8-10, 1994

摘要

The purpose of this workshop was to initiate a dialogue among representatives from industry, government and academia regarding issues of key escrow encryption. Workshop presentations and discussions included current progress in the planned usage of CAPSTONE/CLIPPER chips, the alternative of software key escrowing, multipurpose key escrowing methods, private key escrow management, integrity requirements of application systems, and international implications. The proposed plan of action, arising from this workshop, is to establish a joint industry/government working group to critically evaluate all known key escrowing proposals; examine the adequacy of existing (and possibly suggesting new) vehicles for collaborative industry/government research and development; identify and evaluate suitable algorithms for use in conjunction with key escrow along with criteria for determining acceptability; identify and address the issues of intellectual property which are inherent in any public royalty-free usage of algorithms, key escrow methodology, and supporting infrastructure; and create a key escrowing task force to manage and expedite the search for key escrow alternatives.
