Hi all,
working on draft-ietf-uta-tls13-iot-profile, Thomas and I have
been looking at the implementation status of TLS/DTLS extensions
on embedded devices. Here is what we found out looking at
various popular stacks. There are lots of features in prototype
status and we have not taken those into account.
"red" means not implemented, "green" refers to an implemented
feature, and "white" is an indication that we didn't have a
chance to figure out whether the feature is supported or not
because it was not described in the documentation.
In a nutshell, it is fair to say that certificate and PSKs are
well supported. Raw public key support is also available with a
number of implementations.
What is a bit disappointing is that many extensions targeting
IoT optimizations are not implemented. It is hard to say why.
Maybe companies don't feel a need to use these optimizations,
maybe the optimizations aren't good enough, or companies are
unaware of these RFCs.
Please let us know if we got something wrong or if we forgot
your implementation.
for future comparisons, could you add which versions of those libraries
did you look at?
