Using TLS in Applications (uta) Internet Drafts


      
 TLS/DTLS 1.3 Profiles for the Internet of Things

 Date: 20/10/2024
 Authors: Hannes Tschofenig, Thomas Fossati, Michael Richardson
 Working Group: Using TLS in Applications (uta)
This document is a companion to RFC 7925 and defines TLS/DTLS 1.3 profiles for Internet of Things devices. It also updates RFC 7925 with regards to the X.509 certificate profile and ciphersuite requirements.
 New Protocols Must Require TLS 1.3

 Working Group: Using TLS in Applications (uta)
TLS 1.2 is in use and can be configured such that it provides good security properties. TLS 1.3 use is increasing, and fixes some known deficiencies with TLS 1.2, such as removing error-prone cryptographic primitives and encrypting more of the traffic so that it is not readable by outsiders. For these reasons, new protocols must require and assume the existence of TLS 1.3 existence. This prescription does not pertain to DTLS (in any DTLS version); it pertains to TLS only. This document updates [RFC9325].

Charter for Working Group

There is a renewed and urgent interest in the IETF to increase the security of transmissions over the Internet. Many application protocols have defined methods for using TLS to authenticate the server (and sometimes the client), and to encrypt the connection between the client and server. However, there is a diversity of definitions and requirements, and that diversity has caused confusion for application developers and also has led to lack of interoperability or lack of deployment. Implementers and deployers are faced with multiple security issues in real-world usage of TLS, which currently does not preclude insecure ciphers and modes of operation.

This WG has the following tasks:

  • Update the definitions for using TLS over a set of representative application protocols. This includes communication with proxies, between servers, and between peers, where appropriate, in addition to client/server communication.

  • Specify a set of best practices for TLS clients and servers, including but not limited to recommended versions of TLS, using forward secrecy, and one or more ciphersuites and extensions that are mandatory to implement.

  • Consider, and possibly define, a standard way for an application client and server to use unauthenticated encryption through TLS when server and/or client authentication cannot be achieved.

  • Create a document that helps application protocol developers use TLS in future application definitions.

The initial set of representative application protocols is SMTP, POP, IMAP, XMPP, and HTTP 1.1. It is expected that other protocols that use TLS might later be updated using the guidelines from this WG, and that those updates will happen through other WGs or through individual submissions.

The WG will make the fewest changes needed to achieve good interoperable security for the applications using TLS. No changes to TLS itself will be made in this WG, and the WG will ensure that changes to current versions of popular TLS libaries will not be required to conform to the WG's specifications.

This WG will collaborate with other IETF WGs, in particular with the TLS and DANE WGs.
