Trustor and trustee relationship can be represented by receiver and sender relationship. It is plausible trustee
provides trustworthy data to make a trustor trust in a trustee. For example, home appliance devices (trustee)
provide energy-related data for users (trustor) to control these devices in use case of home energy
management. In this sense, trustee is an information sender and trustor is a receiver.

6 A strategy for trust provisioning of ICT infrastructure, services and applications
This section proposes trust taxonomy in different domains in order to identify important issues for trust
provisioning in the ICT infrastructure, services and applications, and describe a strategy for solving these
issues, particularly considering trust provisioning process.
Trust and reputation are the pillars of many social phenomena that shape the Internet socio-economic scene.
It is important to have a big picture of Trust in the future network in order to successfully develop and deploy
trust into applications and services of ICT infrastructure. Figure 1 is the taxonomy providing initial insights
into the ways trust benefits can be felt.
