Zero Trust Engineering — Key management and cryptographic custody

/02 About

Data and information protection engineering reference for key management and cryptographic custody, including policy, logical interfaces, recovery and assurance.

Purpose: Key management and cryptographic custody. Domain: Data and information protection. Family: lifecycle. Scenario trigger: Generate, access, rotate or retire information encryption key. Input assurance: Key owner, custody domain and authenticated usage intent. Evaluation: Validate key lifecycle transition and purpose constraints. Governing policy: Cryptographic custody, segregation and destruction policy. Resource-side obligation: Issue or revoke narrowly scoped key authorization. Protected concern: Enterprise key custody boundary. Logical interface: Key identity purpose custody attestation lifetime and destruction. Evidence: Key generation rotation access and destruction audit. Failure: Custody compromise, revoked key or unapproved export. Required recovery: Suspend key use and execute controlled rekey procedure. Architectural invariant: Key custody and data authorization are independent enforceable responsibilities 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.
