Dear all,

we have updated our draft on extended session resumption mechanisms for DTLS. The main focus of this draft is to reduce the computation and transmission overhead for constrained clients or servers if a DTLS session cannot be kept open indefinitely.

In this updated version, we added three descriptions of possible usage scenarios, where we believe session resumption to be highly beneficial. Furthermore, we added a section on how minimal session tickets could be structured.

While this draft may not fully satisfy the current scope of DICE, we would be glad to receive feedback regarding the described (and maybe additional) usage scenarios. After getting feedback from people in this WG (with focus on constrained network environments), we then plan to propose our DTLS protocol extension in the DTLS WG.

> Abstract:
>   This draft defines two extensions for the existing session resumption
>   mechanisms of TLS that specifically apply to Datagram TLS (DTLS) in
>   constrained network environments.  Session resumption type
>   negotiation enables the client and the server to explicitly agree on
>   the session resumption mechanism for subsequent handshakes, thus
>   avoiding unnecessary overheads occurring with the existing
>   specifications.  Session resumption without client-side state
>   additionally enables a constrained DTLS client to resume a session
>   without the need to maintain state while the session is inactive.
>   The extensions defined in this draft update [RFC5077] and [RFC5246].
