1. Introduction
EDHOC [I-D.selander-lake-edhoc] is a new protocol for autentication
and key derivation that has been proposed as an alternative in IoT to
provide a secure exchange in an end-to-end fashion. This key
material can be futher used to run other protocols such as OSCORE, as
well as providing key material to any other protocol that needs pre-
shared key material to secure the communications. Provides
authentication and key material generation, which are basic pillars
to the design of an EAP method. And indeed the most important thing
is that it is lightweight and designed for IoT. In addition, the
EDHOC implementation that exists on the device can be reused to
establish OSCORE Security Associations (SAs) for the authentication
process. EAP is a protocol that allows to implement different
authentication mechanims, provides a framework for key management and
has integration with AAA infrastructures. For these reasons, this
new EAP method will allow the different applications and use cases to
take advantage of EAP.
1.1. Requirements Language
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119 [RFC2119].
2. Protocol Overview
2.1. The EAP-EDHOC Conversation
The exchange of messages befalls between two entities that EDHOC
identifies as Initiator (I) and Responder (R). In this EAP method,
