Describe the strict hierarchy trust model.

What will be an ideal response?

In a strict hierarchy trust model, there is one trust anchor (root) from which trust extends. The root is not a starting point for a network, for communication, or for architecture; it is a starting point of trust. Zero or more subordinate trust anchors could extend from the root downward, and the leaves representing end entities are at the bottom. We can consider the model as a big trust tree. Subordinate trust anchors may certify trust in themselves, or they may certify yet other subordinate trust anchors that certify trust in turn. The leaf, or end entity's, trust is verified by tracing backward from its certifier to other subordinate trust anchors until the root is found.
