Draft:ARINC 853

From Wikipedia, the free encyclopedia

ARINC 853 is a standard published in 2024 to harmonize communication in aircraft cabin systems.

The specification defines the Cabin Secure Media-Independent Messaging (CSMIM) Protocol. CSMIM is intended to provide an industry standard open platform approach to defining networks and the elements contained within them for use within aircraft cabin systems. CSMIM is built upon existing protocols that support Constrained RESTful Environments, for example, CBOR for data representation and MQTT for transport. At the core of CSMIM is the philosophy that supporting the interoperability of equipment from many suppliers on a common communications platform is vital. Components that are envisioned to be users of CSMIM in the future will include lighting, sensors, seats, and other cabin systems. The protocol provides device classifications, use cases, and reference architectures to aid developers in adopting and developing networks and hosted elements that will leverage CSMIM. A CSMIM compliant system will provide common services, which are defined in the document, to allow system components to securely join and share data across the network.[1]

In order to harmonize exchanged data, an ontology has been started in the working group in collaborative manner. Proposals can be made and discussed in the public Knowledge Base.
