Certificate validation and channel binding


Abstract

A constrained network entity may determine, via an authentication procedure with a core network entity, the trustworthiness of an endpoint attempting to establish a secure channel with the constrained network entity. The constrained network entity may receive a certificate from the endpoint attempting to establish the secure channel and the constrained network entity may send the certificate asserted by the endpoint to a core network entity for validation. The core network entity may receive the certificate during a key exchange with the constrained network entity and the core network entity may indicate to the constrained network entity the validity of the certificate. The constrained network entity may determine whether to establish the secure channel with the endpoint based on the validity of the certificate.
