[wakaama-dev] Secure bootstrapping with tests/secureclient

[Bill Silverajan <bilhanan.silverajan@xxxxxx>]

Hi all,

Thanks to some of the people on the list, I've successfully bootstrapped 
the lwm2mclient ("testlwm2mclient") against wakaama's own bootstrap server.

I then proceeded with testing secure bootstrapping, with the 
secureclient ("testsecureclient") against leshan's bootstrap server and 
a separate dtls-enabled lwm2m server from leshan.

My setup is simple: The dtls client contacts the bs server, obtaining 
the PSK material for secure registration and communication with the 
lwm2m server.

I've configured the BS server to deliver the necessary credentials to 
testsecureclient, which then proceeds to contact and successfully 
register over DTLS to an external LWM2M server. I was able to accomplish 
bootstrapping over port 5683 for this.

Does the secureclient have the ability to perform secure bootstrapping?

I imagine it's a trivial matter to invoke secureclient with the -i and 
-p flags so that secure bootstrapping is done against the leshan 
bootstrap server. Then, the bootstrap server provides the PSK key of the 
actual LWM2M server to the client.

But I'm unable to discover what the identity/key combination to 
successfully let secureclient communicate with the bootstrap server on 
port 5684 is. Or in fact even where to provide this to the leshan 
bootstrap server!

If I should pose this question to the leshan list (since it might be an 
implementation-specific issue with the bootstrap server), I apologise in 
advance.

Regards,
Bill
