Zero Trust Engineering — Authentication protocol and assertion exchange

/02 About

Identity and access engineering reference for authentication protocol and assertion exchange, including policy, logical interfaces, recovery and assurance.

Purpose: Authentication protocol and assertion exchange. Domain: Identity and access. Family: exchange. Scenario trigger: Initiate authentication assertion exchange. Input assurance: Protocol handshake, relying audience and channel binding. Evaluation: Verify assertion integrity and authentication context. Governing policy: Assertion acceptance, replay and token-binding policy. Resource-side obligation: Deliver short-lived authenticated session assertion. Protected concern: Protected application authentication interface. Logical interface: Authentication request proof challenge response assertion and nonce. Evidence: Protocol transaction replay and assertion audit. Failure: Replay, downgrade or invalid audience claim. Required recovery: Reject handshake and request fresh proof. Architectural invariant: Protocols must bind claims to intended audience, time and authenticated context Adoption: replace reference roles with concrete owner-controlled services. Specify exact provider/consumer identities, schema fields and classifications, signal provenance and freshness, idempotency, authorization lifetime, timeout/retry limits, observation and tamper evidence. A denied or failed operation must not silently become a permitted one. Scope: original vendor-neutral, implementation-agnostic technical reference model. Illustrative logical components and behaviors are neither a deployed system nor evidence of regulatory compliance. Package identities remain stable within the package; cross-package semantic reconciliation requires separate explicit registry support.
