Group Management

System Management > Group Management

This section is used to set up and maintain issuer groups. It provides access to the same functions as the Issuer Management section, but from an issuer group perspective.

Organising related issuers in a group can greatly reduce the issuer administration overhead. Groups can have their own keys (AAV key1, CVC2 keys2, CVV keys3, IAV HMAC keys4 and signing key5) and certificates. An issuer can be configured to use the parent group's keys to reduce the number of keys generated and as a result, also reduce the overhead of key management tasks for synchronizing multiple hardware security modules. An issuer may also be configured to use the parent group's certificate in order to reduce the overhead of certificate management and renewal.

A list of issuer groups and their issuer and group members is displayed. You can browse to view issuer group and issuer details by clicking on the Group Name, Issuer Members and Group Members links.
