Figure 1 – Overall Trust Taxonomy in different domains

Due to huge domain of trust usages, there are a large number of challenges for designing, developing and
deploying a trust platform for ICT systems. This section follows the structure of the overall trust taxonomy as
illustrated in Figure 1 for briefly describing trust provisioning strategies of ICT infrastructure.

6.1 Understanding of Trust Taxonomy
Generally, trust involves in all aspects and in all perspectives of any systems. For example, in perspective of
Networking Domain, trust can be provisioned into Security, Region, and Element aspects as illustrated in the
Figure 18. There are four basic domain perspectives, namely Networking Domain, Architecture Domain,
System Domain and Services/Apps Domain. In each domain, there are some aspects in which trust can play
a role for better improvements. It is necessary to consider trust design, trust development and trust
deployment by breaking down to all necessary processes.
Basically, the required number of processes of trust provisioning is different from each domain and each
aspect. And the detailed specification of each provisioning process is also different among these domains
aspects. However, the generic trust provisioning is same as in all domains and aspects. A trust infrastructure
consists of 8 fundamental processes as illustrated as “Trust Provisioning Process” category in the Trust
Taxonomy figure. They are Data Collection, Data Access Control and Data Parsing, Data Process and Trust
Analytic, Reputation and Trust Processing, Trust Establishment, Trust Computation, Trust Management and
Decision Making.

In the remaining of this section, it describes in details of all the Trust Provisioning Processes. These processes
are generic and used for all domains in the trust taxonomy. After that, it briefly mentions several domain-
specific trust provisioning strategies in each particular domain.
