Long-Term Validation for JSON Web Signature (LTV-JWS)

This repository contains the working files for the Internet-Draft:

Long-Term Validation for JSON Web Signature (LTV-JWS)

• Draft: draft-miyachi-ltv-jws
• Author: Naoto Miyachi
• Status: Individual Internet-Draft
• Intended Status: Informational

Abstract

LTV-JWS extends JSON Web Signature (JWS) with lightweight long-term validation capabilities.

The specification defines:

• Signature levels (SIG-B, SIG-T, SIG-LTV, SIG-LTA)
• RFC 3161 timestamps
• Embedded validation information (certificates, CRLs, OCSP responses)
• Archive timestamps for long-term preservation
• External references (refs) for indirect signing of arbitrary data

The design preserves the existing JWS processing model while enabling long-term validation similar to XAdES for XML signatures.
