4.1 OPC UA Security Object Model

A CertificateGroup is a context that contains a TrustList and one or more CertificateTypes that can be assigned to an Application (See OPC 10000-12).

This ObjectType allows an Application which has multiple TrustLists and/or ApplicationInstance Certificates to express them in its AddressSpace.

Figure 1 depicts the OPC UA security object model.
