A Trust Model is the collection of rules that inform application on how to solve the legitimacy of a Digital Certificate. According to the ITU-T X..
What are types of trust model?
1 Direct Trust. Direct trust is the simplest and most basic form of trust model, where each entity in a network trusts only itself and those that it has explicitly verified. 2 Third-Party Trust. 3 Hierarchical Trust. 4 Web of Trust. 5 Hybrid Trust. 6 Here's what else to consider..
What is a trust model in cryptographic systems?
A trust relationship based upon public-key cryptography technology is intended to ensure the authenticity of the second entity's identifying descriptor and the enforceability of commitments undertaken by both entities. A trust model is used to describe these trust relationships..
What is cryptography models?
Cryptographic schemes are usually based on complexity assumptions, which state that some problems, such as factorization, cannot be solved in polynomial time. Schemes that can be proven secure using only complexity assumptions are said to be secure in the standard model..
What is trust Modelling?
A trust model measures the security strength and computes a trust value. A trust value comprises of various parameters that are necessary dimensions along which security of cloud services can be measured. CSA (Cloud Service Alliance) service challenges are used to assess security of a service and validity of the model..

A trust relationship based upon public-key cryptography technology is intended to ensure the authenticity of the second entity's identifying descriptor and the enforceability of commitments undertaken by both entities. A trust model is used to describe these trust relationships.
In cryptography, a trusted third party (TTP) is an entity which facilitates interactions between two parties who both trust the third party; the third party reviews all critical transaction communications between the parties, based on the ease of creating fraudulent digital content. In TTP models, the relying parties use this trust to secure their own interactions. TTPs are common in any number of commercial transactions and in cryptographic digital transactions as well as cryptographic protocols, for example, a certificate authority (CA) would issue a digital certificate to one of the two parties in the next example. The CA then becomes the TTP to that certificate's issuance. Likewise transactions that need a third party recordation would also need a third-party repository service of some kind.

Mechanism for authenticating cryptographic keys
In cryptography, a web of trust is a concept used in PGP, GnuPG, and other OpenPGP-compatible systems to establish the authenticity of the binding between a public key and its owner. Its decentralized trust model is an alternative to the centralized trust model of a public key infrastructure (PKI), which relies exclusively on a certificate authority. As with computer networks, there are many independent webs of trust, and any user can be a part of, and a link between, multiple webs.
