Cryptographic Service Provider

Definition

A Credential Service Provider is a trusted entity that issues or registers subscriber tokens and electronic credentials. CSPs play a crucial role in authentication systems, particularly in federated authentication systems where they may act as independent third parties or issue credentials for their own use³⁴.

1. Registration**: The CSP registers a subscriber by verifying their identity, often through a Registration Authority (RA).
2. Token Issuance**: The subscriber is given a token, which is used in authentication protocols.
3. Credential Issuance**: The CSP issues electronic credentials that bind the token to the subscriber's identity or other verified attributes.
4. Authentication**: The CSP manages the subscriber’s primary authentication credentials and issues assertions derived from those credentials³⁴.

CSPs are essential for ensuring secure and reliable authentication processes, especially in environments where multiple services and applications require user authentication.
