Abstract:

   Autonomous machines such as uncrewed aircraft, ground robots, and
   spacecraft execute commands issued by human operators and,
   increasingly, by AI agents.  When an incident occurs, no independent
   evidence exists of which commands the machine received: conventional
   logs are mutable by the operating party, symmetric message
   authentication codes cannot demonstrate origin to a third party, and
   records signed with elliptic-curve cryptography lose their
   evidentiary value once cryptographically relevant quantum computers
   exist.

   This document defines the Anchor: a post-quantum digital signature
   over a compact commitment to a window of authenticated machine
   traffic.  An anchor chain constitutes a tamper-evident, non-
   repudiable record of what a machine was commanded to do and what it
   reported back, verifiable by any third party without trusting the
   operator, without network access at recording time, and with security
   that survives the quantum transition.  The construction is protocol-
   agnostic and is designed for bandwidth-constrained links where per-
   message post-quantum signatures are impractical.
