摘要：A system and method of relating a public key to a compact identification string

in a digital certificate to enable an entity to construct a certificate chain from a rootcertificate authority to an end-entity efficiently and further allow a certificate holder tostore only its identifier, thus providing privacy protection, and present this in place of adigital certificate for authentication rather than storing and presenting its certificate or achain of certificates representing the certificate path up to the root certificate authority.In a preferred embodiment, the certificate authority generates unique identifier for eachcertificate consisting its pseudonym concatenated with the pseudonyms of other sub-certificate authorities in the certificate chain between it and the certificate holder,concatenated with certificate holder's pseudonym. The pseudonyms are generated bythe entity known by the pseudonym or the entity certifying a binding between thepseudonym and the entity's public key.
