SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps developers and systems implement robust verification of token statuses, ensuring that referenced tokens are valid and up-to-date according to EUDI specifications.

Core Features & Use Cases

  • Token Status Verification: Implement logic to check the status of referenced tokens (JOSE/COSE).
  • Status List Integration: Understand how to reference and query Status List Tokens for status information.
  • Use Case: A relying party needs to verify a Verifiable Credential presented by a user. This skill guides the process of checking if the credential's referenced token is still valid or has been revoked by consulting the appropriate status list.

Quick Start

Use the token-status-list-usage skill to understand how to verify the status of a JOSE token.

FAQPage Schema
How do I verify token status for a JOSE or COSE credential?▼

To verify token status, you reference the status list token associated with the JOSE or COSE credential and check its index to determine if the token is valid, invalid, or suspended.

What is a status list token in EUDI Wallet interactions?▼

A status list token is a centralized reference structure that records the validity states of multiple tokens. It allows relying parties to efficiently query whether a presented credential is revoked or active.

When do I need to check token validity against a status list?▼

You need to check token validity when a relying party receives a Verifiable Credential and must confirm the credential has not been revoked or suspended by the issuer before accepting it.

How do I handle suspended or invalid tokens during credential verification?▼

You handle suspended or invalid tokens by applying the validation rules defined for the status list, querying the referenced index to detect the token's lifecycle state and rejecting credentials marked invalid.

Can I use this token verification approach for both JOSE and COSE formats?▼

Yes, the token status verification procedures support both JOSE and COSE formats, detailing specific validation rules for checking referenced tokens and status types within either format.
