CoRE Resource Directory

Regular resource discovery GET coap : / / [ fd02 : : fd ] / . well − known/ core ? r t=temperature Response : 2.05 Content from [2001: db8 : f0 : : 1 ] Payload : < /temp > ; r t=temperature ; ct=0

Registration at Resource Directory POST coap : / / [ 2 0 0 1 : db8 : f01 : : f f ]/ rd ?ep=node42&l t =300 from [2001: db8 : f0 : : 1 ] Payload : < /temp > ; r t=temperature ; ct=0 Response : 2.04 Changed

Discovery via Resource Directory GET coap : / / [ 2 0 0 1 : db8 : f01 : : f f ]/ rd − lookup / r e s ? r t=temperature Response : 2.05 Content Payload : < coap : / / [ 2 0 0 1 : db8 : f0 : : 1 ] / temp > ; r t=temperature ; ct =0; anchor=”coap : / / [ 2 0 0 1 : db8 : f0 : : 1 ] ”

OSCORE Object Security for CoRE

OSCORE request protection GET coap :// node42 . example . com/ ambient / Token : ”0123” Observe : yes POST coap :// node42 . example . com/ Token : ”0123” Observe : yes Object − S e c u r i t y : key ID , nonce Encrypted payload : GET / ambient / the AEAD tag

OSCORE response protection 2.05 Content Token : ”0123” Observation update : 15 Payload : a i r i s s t i l l hot but not as dry any more 2.04 Changed Token : ”0123” Observation update : 15 Object − S e c u r i t y : empty Encrypted payload : 2.05 Content , Payload : a i r i s s t i l l hot but not as dry any more AEAD tag

Recap ◮ Resource Directory: discovery where multicast won’t do ◮ OSCORE: compact end to end protected exchanges across proxies ◮ SenML, Links-CBOR: compact versatile media types ◮ CoREConf, PubSub, CoRE interfaces: application building blocks
