Trust Models

Trust Models

Trust models refer to frameworks that are used to establish trust between two or more parties. These models are essential for ensuring that communication and transactions between parties are secure and reliable. Trust models are used in various applications, including e-commerce, social networking, and cloud computing. One common trust model used in e-commerce is the public key infrastructure (PKI), which uses digital certificates to verify the identity of parties involved in a transaction.

Another trust model commonly used is the web of trust (WoT), which is used in peer-to-peer networking and email encryption. The WoT model relies on the concept of reputation, where users assign a trust rating to other users based on their personal experiences. This model helps to establish trust between parties that may not have a direct connection, as it allows users to rely on the recommendations of others in their network.

Finally, the federated identity model is used to establish trust between different organizations or domains. In this model, each organization maintains its own authentication system, but users can access services from other organizations using a single set of credentials. This model is commonly used in cloud computing and allows users to access services from different providers without having to create multiple accounts or credentials. Overall, trust models are essential for ensuring the security and reliability of transactions and communications in various applications.

Companies follow one or another trust model, which dictates how users will go about establishing certificate validity. There are three different models:

• Direct Trust
• Hierarchical Trust
• A Web of Trust
