ATTRIBUTE INFORMATION VERIFICATION METHOD, REVOCATION INFORMATION GENERATING APPARATUS, SERVICE PROVISION SOURCE APPARATUS, AND ATTRIBUTE INFORMATION VERIFICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an attribute information verification method, a revocation information generating apparatus, a service provision source apparatus, and an attribute information verification system capable of enhancing the convenience of a user by relieving a processing load in the case of managing the revocation of an attribute certificate on which a plurality of attribute information items are described.

SOLUTION: A sequence diagram indicating operations of a charging information verification system 1 includes: a step S110 wherein an ACRL management apparatus 120 generates partial revocation information representing a revocation state of attribute information included in an attribute certificate and stores the generated partial revocation information; a step S102 or the like wherein a user terminal 20 transmits the attribute certificate to a server 30; a step S105 or the like wherein the server 30 collates the partial revocation information stored in the ACRL management apparatus 120 with the attribute information included in the attribute certificate received from the user terminal 20 to verify the validity of the attribute information; and a step S106 wherein the server 30 acquires the attribute information verified to be in a valid state.
