Security Documentation Requirements

Minimum security documentation required before any revived component can be described as supported.

1. Required documentation

  • •Threat model and trust boundaries.
  • •Authentication and key-management design.
  • •Dependency and update policy.
  • •Supported versions and security-fix expectations.
  • •Responsible vulnerability disclosure process.

2. Release requirements

  • •Automated tests for security-sensitive behaviour.
  • •Review of externally reachable interfaces.
  • •Signed or otherwise verifiable release artifacts.
  • •Accurate record of known limitations.
  • •No unsupported privacy or encryption claims.

3. Historical warning

Historical ZRTP and secure-calling material remains valuable technical history. It must not be interpreted as a security assessment of any future implementation.
