Trustworthiness Vectors for the Software Updates of Internet of Things
(SUIT) Workflow Model
draft-birkholz-rats-suit-claims-01
Abstract
The IETF Remote Attestation Procedures (RATS) architecture defines
Conceptual Messages as input and output of the appraisal process that
assesses the trustworthiness of remote peers: Evidence and
Attestation Results. Based on the Trustworthiness Vectors defined in
Trusted Path Routing, this document defines a core set of Claims to
be used in Evidence and Attestation Results for the Software Update
for the Internet of Things (SUIT) Workflow Model. Consecutively,
this document is in support of the Trusted Execution Environment
Provisioning (TEEP) architecture, which defines the assessment of
remote peers via RATS and uses SUIT for evidence generation as well
as a remediation measure to improve trustworthiness of given remote
peers.
