Title Electronic Signatures and Trust Infrastructures (ESI); Selective disclosure and zero-knowledge proofs applied to Electronic Attestation of Attributes; Part 3: EUDI Wallet Unit Attestation (WUA)
STF705 D2.16 (EC TS3) SD and ZKP applied to EAA; EUDI WUA 
Scope and Field
of Application
Specify the following:
- The WUA (Wallet Unit Attestation) is logically comprised of WKAs (Wallet Key Attestations) and WIAs (Wallet Instance Attestations).
- The WIA is an attestation that attests the integrity and authenticity of the wallet instance and provides information about the wallet instance.
- The WKA contains attested information about the security of cryptographic keys stored in a Wallet Unit’s key storage.
- The format of WKAs and WIAs including its encoding and integrity protection mechanism.
- The content of WKAs and WIAs.
- The life-cycle of WKAs and WIAs.
- The revocation information provided within the WKAs and WIAs.
- Signature algorithms of WIA and WKA.
- Certificate policies of WIA and WKA signer certificates.
Note: The transfer of WKAs and WIAs between the EUDIW and the issuing party (i.e., either PID Provider or Attestation Provider) is out of scope. Instead ETSI TS 119 472-3 will apply.
