Abstract:
1. A method for managing a Certificate Revocation List (CRL), the method comprising: receiving at a first device the CRL, the CRL comprising at least two revoked certificate identifiers, wherein the first device is a smartcard and at least one of the two revoked certificate identifiers is a serial number of a revoked certificate; partitioning the CRL into at least two entries, wherein each entry of the partitioned CRL comprises a plurality of certificate revocation identifiers of the CRL; calculating, at the first device, for each entry of the partitioned CRL, an integrity field associated with a respective entry of the CRL using a secret data, wherein each integrity field is a code used to authenticate the associated entry of the associated CRL independent of other entries in the associated CRL; transmitting to a second device, distinct from the first device, the at least two entries and the integrity fields associated with the at least two entries; and storing into the second device the transmitted entries and the associated integrity fields.
