Abstract:

   This document defines an application profile of the Agent Trust
   Transport Protocol (ATTP) [draft-sharif-attp-agent-trust-transport]
   for use in Industrial Control Systems (ICS), Supervisory Control
   and Data Acquisition (SCADA) environments, and Internet of Things
   (IoT) deployments.  It specifies how ATTP mandatory message signing,
   agent identity passports, and trust-gated access control apply to
   industrial protocols including Modbus/TCP, OPC UA, MQTT, and CoAP.

   The profile addresses the absence of per-message authentication in
   legacy industrial protocols, which has been exploited in numerous
   critical infrastructure attacks.  It defines a gateway architecture
   that enables ATTP protection for legacy devices without firmware
   modification, maps ATTP trust levels to IEC 62443 Security Levels,
   and specifies real-time revocation mechanisms suitable for
   safety-critical environments.
