Explanation:
In a bridge trust model allows lower level domains to access resources in a separate PKI through
the root CA.
A trust Model is collection of rules that informs application on how to decide the legitimacy of a
Digital Certificate.
In a bridge trust model, a peer-to-peer relationship exists among the root CAs. The root CAs can
communicate with one another, allowing cross certification. This arrangement allows a certification
process to be established between organizations or departments.
Each intermediate CA trusts only the CAs above and below it, but the CA structure can be
expanded without creating additional layers of CAs.
