Hi all,

Yesterday I submitted version -04 of the DTLS 1.2 CID draft. On the working group Github issue tracker we spent a long time discussing how the MAC calculation should be changed to include the cid/cid_length information. In version -03 we only provided a description how to use the CID functionality with AEAD ciphersuites. In version -04 we also included a description for non-AEAD ciphersuites as well. Since the description became a bit convoluted we improved the language and the representation of the record layer protection and of the record layer format. We hope that implementers will find the -04 version easier to read.

Here is the draft:

Here is the diff:
https://tools.ietf.org/rfcdiff?url2=draft-ietf-tls-dtls-connection-id-04.txt

We have been doing interop testing this year while editing the spec. If you want to test your code please drop me an email or take a look at https://github.com/tlswg/dtls-conn-id/issues/18

Ciao
Hannes
