Trust Envelope

A Technical Reference

Overview

A Trust Envelope is a structured, tamper-evident evidence object that captures a canonical representation of the trust-state conditions under which an authorization or compliance-relevant event occurs. Its purpose is to provide a stable, verifiable reference to the integrity of the trust-state at a specific point in time, independent of the system that generated it.

Trust Envelopes do not perform authorization. They document trust-state inputs—including integrity values, revocation conditions, dependency relationships, and policy identifiers— that downstream systems may rely on when validating authorization evidence.

By providing a canonical, signed representation of trust conditions, Trust Envelopes enable independent, cross-system verification of whether a decision or event was produced under valid and contemporaneous trust-state constraints.

Purpose

• Independent verification of trust-state conditions
• Evidence portability across heterogeneous systems
• Revocation-aware validation without reliance on enforcement systems
• Deterministic trust-state comparison across participants
• Interoperable trust frameworks across organizational boundaries

Core Components (High-Level)

• Canonicalized trust-state representation
• Cryptographic integrity value
• Policy or rule-set identifier
• Revocation or dependency metadata
• Temporal and replay-protection elements
• Issuer cryptographic signature

Relationship to Authorization Envelopes

Trust Envelopes and Authorization Envelopes function as complementary evidence objects. A Trust Envelope documents the state of trust, while an Authorization Envelope documents the decision produced under that state.
