Abstract
A method which allows implementation of the revocation of public-key certificates facilitates engineering of certificate revocation lists (CRLs). It solves the practical problem of CRLs potentially growing to unmanageable lengths by allowing CRLs to be segmented, based on size considerations or priority considerations related to revocation reasons. The method is used to distribute CRL information to users of certificate-based public-key systems. It is also applied more generally to update any field in a certificate by reference to a secondary source of authenticated information.
