Question

Quizplus · Accepted Answer

The Web of Trust is a decentralized model for authenticating the identities of users and ensuring the integrity of messages exchanged between those users. In a web of trust, people can securely send messages to their friends because the authenticity of each user's identity has been verified and vouched for by other trusted users within the web. This stands in contrast to a Certificate Authority, which is a centralized system for verifying the authenticity of users' identities, or a PKI (Public Key Infrastructure), which is a set of protocols and tools for securing communications using public key cryptography. A "Digital ring" is not a standard term in the world of cryptography and security.
