Re: [leshan-dev] no response after client hello with server rpk mode onl

[Simon Bernard <contact@xxxxxxxxxxxxxxx>]

Leshan does not support Server authentication only (I mean without client authentication).

I don't think the LWM2M specification allow this.

May I ask what exactly is your use case ?

Hi,

>The leshan-server-demo supports only PSK and RPK

Thanks for your reply.

Let me rephrase my question.

For rpk , I test the case

"Client and Server Use Raw Public Keys"

(cf https://tools.ietf.org/html/rfc7250#section-5.2 )

and handshake is ok (see Fig.1 below).

I test another one , which is the case "

Server Uses a Raw Public Key"

(cf. https://tools.ietf.org/html/rfc7250#section-5.1 ).

My question is here.

If client does not use a raw public and server use a raw public,

it seems leshan-server doesn't work properly after client hello in handshake protocol.

Hello Verify Request doesn't come from server. (see Fig.2 below)

Does leshan-server or leshan-server-demo supports

both "Client and Server Use Raw Public Keys" case and

"Server Uses a Raw Public Key" case?

Thanks,

Joseph

Hi,

   The leshan-server-demo supports only PSK and RPK. (x509 is not supported)

Hi, all

I modified the wakaama client for supporting rpk mode (both server and client)

and sucessfully work with leshan server.

But I have no respone after client hello in handshake protocol for setting server rpk mode only.

Using wireshark I checked extension client_certificate_type info is omitted in client hello

and other info. is same as rpk mode supporting both server and client side.

My question is  "Doesn't leshan server support server rpk mode only?"

FYI, I use leshan server version getting from here

Thank you.
