Identity Escrow

Joe Kilian and Erez Petrank

Abstract

We introduce the notion of escrowed identity, an application of key-escrow ideas to the problem of identification. In escrowed identity, one party, A, does not give his identity to another party B, but rather gives him information that would allow an authorized third party, E, to determine A's identity. However, B receives a guarantee that E can indeed determine A's identity. We give protocols for escrowed identity based on the El-Gamal (signature and encryption) schemes and on the RSA function. A useful feature of our protocol is that after setting up A to use the system, E is only involved when it is actually needed to determine A's identity.
