Relying Party

A Relying Party (RP) is a term commonly used in the field of computer security and authentication protocols. It refers to an entity or system that relies on the services provided by an identity provider (IdP) to authenticate and authorize users.

Overview

In the context of authentication protocols such as OpenID or SAML, a relying party is typically a website or application that allows users to log in using their existing credentials from a trusted identity provider. The relying party delegates the responsibility of user authentication to the identity provider, which verifies the user's identity and provides the relying party with the necessary information to grant access.

Functionality

The primary function of a relying party is to verify the authenticity of a user's identity. When a user attempts to log in to a relying party, the relying party redirects the user to the identity provider's authentication page. The user then enters their credentials, which are securely transmitted to the identity provider for verification.

Once the identity provider confirms the user's identity, it generates an authentication token or assertion, which is sent back to the relying party. The relying party validates the token and grants the user access to the requested resources or services.

Categories

Relying parties can be categorized based on the type of authentication protocols they support. Some common categories include:

• Single Sign-On (SSO) Relying Parties: These relying parties support protocols like SAML or OpenID Connect to enable users to log in once and access multiple applications or services without the need for separate authentication.

• Federated Identity Relying Parties: These relying parties participate in a federation, where multiple organizations trust each other's identity providers. They rely on federated identity protocols like SAML or OAuth to establish trust and enable seamless authentication across different organizations.

• Multi-factor Authentication (MFA) Relying Parties: These relying parties require users to provide multiple forms of authentication, such as a password and a one-time password (OTP), to enhance security and prevent unauthorized access.

Templates

Templates can be used to standardize the formatting and structure of relying party articles. Some commonly used templates include:

• {{

Infobox Software}} : This template provides a standardized format for presenting key information about relying party software, such as its developer, initial release date, and latest version.

• {{

Citation needed}} : This template is used to indicate that a specific statement or claim in the article requires a reliable source citation.

• {{

Cleanup}} : This template is used to flag sections of the article that require cleanup or improvement.

Conclusion

Relying parties play a crucial role in the authentication process, allowing users to securely access resources and services by relying on trusted identity providers. By delegating the responsibility of user authentication to identity providers, relying parties can focus on providing valuable services while ensuring the security and privacy of their users' identities.
