Annex D: Informative Reference Mapping

This annex identifies categories of external frameworks that address requirements similar to those in this guide. The mapping is non-normative and is intended to assist implementers in understanding where SEDI requirements align with, diverge from, or go beyond existing frameworks.

The selection of specific standards is delegated to conformance profiles (see Chapter 14). Conformance profiles SHOULD include detailed mappings to the specific standards they adopt. See the Introduction for the current list of candidate technologies under consideration for profiles.

D.1 Identity Proofing Frameworks

SEDI Requirement	Framework Category	Notes
SEDI-IDP-01	Identity assurance level frameworks	Utah statute requires "generally accepted standard"; a conformance profile must specify which assurance level framework applies and at what level
SEDI-IDP-04	Evidence collection and validation standards	Four proofing objectives (existence, identity, binding, record) map to standard evidence requirements in established proofing frameworks
SEDI-SDI-06	Federation and assertion frameworks	Online presentation has parallels to federated assertions; offline presentation has no direct equivalent in most proofing frameworks
SEDI-SDI-17	Privacy requirements in proofing standards	SEDI's statutory anti-surveillance prohibition is more absolute than the privacy guidance in most identity frameworks

D.2 Digital Identity Wallet Architectures

SEDI Requirement	Architecture Category	Notes
SEDI-SDI-03	Unlinkability and pseudonym mechanisms	Various architectures address unlinkability through pseudonyms, batch issuance, or cryptographic blinding
SEDI-SDI-06	Proximity and remote presentation flows	Most wallet architectures define both proximity (offline) and remote (online) presentation modes
SEDI-SDI-07	Selective disclosure mechanisms	Attribute-level selective disclosure is a common requirement across digital credential architectures
SEDI-SDI-08	Predicate proof / zero-knowledge proof mechanisms	Not all credential formats natively support predicate proofs; this is a key differentiator when evaluating candidate technologies
SEDI-SDI-15	Open standards mandates	Most government wallet architectures mandate open standards, though specific standard bodies referenced vary
SEDI-WAL-04	Secure cryptographic device requirements	Wallet architectures vary in how they specify tamper resistance and secure element requirements
SEDI-WAL-06	Data portability and credential export	Portability requirements vary significantly across architectures

D.3 Credential Format Capabilities

Different credential formats offer different capability sets. A conformance profile must demonstrate that its chosen format satisfies all applicable SEDI requirements. Key capability dimensions to evaluate:

SEDI Requirement	Required Capability	Evaluation Question
SEDI-SDI-04	Issuer signature verification	Does the format support cryptographic proof of authenticity verifiable with only the issuer's public key?
SEDI-SDI-06 (offline)	Offline verification	Does the format support verification without network connectivity?
SEDI-SDI-07	Per-attribute selective disclosure	Does the format allow revealing individual attributes without exposing others, cryptographically enforced?
SEDI-SDI-08	Predicate proofs	Does the format support boolean assertions (e.g., "age >= 21") without revealing the underlying attribute?
SEDI-BOR-11	Contactless presentation	Does the format support presentation without requiring device handover?
SEDI-CRY-02	Holder-controlled key binding	Does the format bind the credential to a holder-generated asymmetric key pair?
SEDI-PRV-01	Unlinkable presentations	Does the format prevent cross-context correlation across presentations to different verifiers?
SEDI-INT-03	Wallet portability	Can credentials in this format be exported and imported across different compliant wallets?
