Credentials Provisioning and Management via EAP (EAP-CPROM)
draft-pala-eap-cprom-00
Abstract
With the increase number of devices, protocols, and applications that
rely on strong credentials (e.g., digital certificates, keys, or
tokens) for network access, the need for a standard credentials
provisioning layer is paramount. In particular, since EAP is
deployed for authentication needs, the authors extend this use-case
by including support for provisioning and management of credentials.
In particular, this specification defines how to support the
provisioning of strong credentials to users and/or devices without
the need for providing IP connectivity. The use of EAP not only for
provisiong but also for managing network credentials provides a
general conduit that can be exploited in different environments
(e.g., Wired and WiFi networks credentials management).

1. Requirements notation
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 [RFC2119].
2. Introduction
Because of the increasing number of highly available and highly
utilized websites that require secure communications to protect the
flow of information from the server to the client and the raising
number of devices (IoT) that require strong authentication
capabilities, the need for a low-cost and efficient approach to
network credentials management is evident.
This specification addresses the problem of providing a simple-to-use
and simple-to-deploy system for credentials management by extending
the EAP protocol to support credentials provisioning and management
functionality.
3. Overview of existing solutions
Currently there are many protocols that address the lifecycle of
credentials. In particular, when it comes to digital certificates,
some of the most deployed management protocols are:

6. IANA Considerations
This document uses a new DEAP type, CPROM, whose value (TBD) MUST be
allocated by IANA from the EAP TYPEs subregistry of the RADIUS
registry.
7. Security Considerations
Several security considerations need to be explicitly considered for
the system administrators and application developers to understand
the weaknesses of the overall architecture.
8. Acknowledgments
The authors would like to thank everybody who provided insightful
comments and helped in the definition of the deployment
considerations.
