Authentication authority

An entity that verifies the identity of non-human identities (NHIs) and manages access to resources.

Description

An authentication authority is a critical component in the management of Non-Human Identities (NHIs), which include devices, applications, and services that require identification and access control. In this context, the authentication authority serves as a trusted entity that verifies the identities of these non-human entities before granting them access to systems, networks, or data. It employs various protocols and mechanisms, such as Public Key Infrastructure (PKI) or OAuth, to ensure that the NHIs are who they claim to be. This is particularly important in the era of the Internet of Things (IoT), where numerous devices operate autonomously and interact with sensitive information and resources. Effective authentication authorities help prevent unauthorized access and ensure secure communication between NHIs, thereby safeguarding an organization's digital assets. As NHIs proliferate, the role of authentication authorities in managing these identities becomes increasingly critical to maintaining security and trust in automated processes.

Examples

  • Digital certificates issued by a Certificate Authority (CA) for IoT devices.
  • OAuth 2.0 authorization servers that authenticate API clients.

Additional Information

  • Authentication authorities can be centralized or decentralized depending on the architecture.
  • They play a vital role in compliance with security standards and regulations.
