hlr-18-combined-presentations-of-attributes

What problem does it solve?

This Skill addresses the EUDI high-level requirements for securely combining multiple attestations or attributes within a Wallet Unit, ensuring cryptographic binding and user verification.

Core Features & Use Cases

• Cryptographic Binding: Implements schemes to prove that multiple private keys are managed by the same Wallet Unit.
• Attestation Issuance: Supports requesting proof of key management during the issuance of new attestations or PIDs.
• User Verification: Ensures that new attestations are legitimately linked to the user's existing identity.
• Use Case: When a user presents a verified identity (PID) and requests a new, specialized attestation, this skill ensures the Wallet Unit can cryptographically prove it manages the keys for both, enhancing trust in the issuance process.

Quick Start

Use the hlr-18-combined-presentations-of-attributes skill to verify the cryptographic binding of attestations for a new issuance request.
