Selective disclosure credential sets

Jason E. Holt and Kent E. Seamons

Abstract

We describe a credential system similar to the electronic cash system described by Chaum, Fiat and Naor. Our system uses bit commitments to create selective disclosure credentials which limit what portions of a credential the holder must reveal. We show how credentials from separate issuers can be linked to the same person in order to prevent users from pooling credentials to obtain services no one user could obtain alone. We also describe how to use a blinding technique described by Laurie which may not violate the patents on blind signatures.

Note: Updates to many sections, rewritten abstract.
