Table of Contents

1. Introduction

The DANE protocol defined in RFC 6698 provides a mechanism for specifying in DNS the Transport Layer Security (TLS) certificate or trust anchor (ex. certificate authority) to be used for a given domain. As the DANE protocol is being more widely deployed, we can observe some of the challenges seen to date. This document attempts to capture some of those observations and poses some questions for further consideration. Feedback on this document is welcome.

2. Observations

As I have been helping people understand the value of using DANE I have observed the following points related to deploying DANE:

There are also questions about the availability of DNSSEC, but as that deployment is increasing on both the signing and validation side and tools are now more readily available, I've chosen here to focus more on observations I have heard directly related to DANE.

3. Questions

Several potential questions for discussion include:

4. IANA Considerations

This document requests no actions from the IANA.

5. Security Considerations

This document raises no specific security considerations.

6. References
