Certificate Trust Model¶

There are 3 different certificate trust models:

Direct Trust

The parties exchange their public keys directly. The trust is established by mapping the keys to an identity

Web of Trust

Each party can trust other parties. Decentralized trust model. Each public key can be signed by multiple parties.

Hierarchical Trust

Trustworthy authorities certify public keys. Each node only accept public keys by their trusted authorities.
