Abstract
Certification will be performed without the use of any external certification organizations in an organization such as an enterprise. A server and a plurality of clients are connected via a network to thereby constitute a certification system for the entire enterprise. A public secondary memory in the server holds a server name, a certificate list, a temporary registrant list and the like. The certificate list includes individual and group certificates, and the certificate includes specifying information on a certification target, a public key and signature by an responsible person of a group, to which the certification target belongs. The group responsible person signs the public key of the group member and specifying information by using the information on a registrant list to generate a certificate.

A certification apparatus for performing a certification for an individual and a group in an organization constructed by hierarchically arranging a group having at least one of an individual and a group as a constituent member, comprising:
- a confirmation process unit that confirms a certification target on the basis of communication between a responsible person of a group and said certification target belonging to said group;
- and
- a certificate generating unit that generates a certificate for said certification target by signing signature-target information including a public key for said certification target and specifying information on said certification target by a private key used by the responsible person of said group.
The certification method for performing certification for an individual and a group in an organization constructed by hierarchically arranging a group having at least one of an individual and a group as a constituent member, comprising the steps of:
- performing a confirmation process for said certification target on the basis of communication between a responsible person of a group and a certification target belonging to said group or the responsible person of said certification target;
- and
- generating a certificate for said certification target by signing information including a public key for said certification target and specifying information on said certification target by a private key of the responsible person of said group.
A computer programmed product for certification used for performing certification for an individual and a group in an organization constructed by hierarchically arranging a group having at least one of an individual and a group as a constituent member, said computer programmed product being used in order to cause a computer system to execute the following steps of:
- performing a confirmation process for said certification target on the basis of communication between a responsible person of a group and the certification target belonging to said group or the responsible person of said certification target;
- and
