The document discusses trust models for public key infrastructures (PKIs) that allow for authentication across large networks. It describes three types of public key authorities and how trust is established between them using mechanisms like hierarchies, bridges, and cross-certification.
This paper presents and compares several trust models currently being considered and applied for use with public-key certificate infrastructures based on the X.509 specification, including subordinated hierarchies, cross-certified meshes, hybrids, bridge CAs, and trust lists.
Of the many different PKI trust models proposed in the literature, some have been implemented and are currently used in practical settings, from small personal networks to large scale private and public networks such as the Internet.
This paper presents different PKI trust models architectures, then analyzes and compares some proposed PKITrust models for e-services applications and describes their implications for trust relationship and trust propagation.
This paper explores the trust models applied by various cryptographic schemes: a) the web of trust employed by Pretty Good Privacy (PGP) where users using their own set of trusted public keys, b) Kerberos, a secret key distribution scheme using a trusted third party, c) certificates, which allow a set of trusted third parties to authenticate ...
