Hi Nat,related to the private key embeded by manufacturer I am wondering who would embed what in the case of a multi-manufacturer.use case:1) thing created by original manufacturer : embed a priv key2) thing crafted/customized (oem) by second manufacturer : embed a priv key when thing will need to act on behalf I expect to reflect a 1 to many relationship at this point and so I'll need as user to decide the degree of relationship between the various keys or only one single key pair will be allowed and this means we need to define a hierarchical policy to decide who will embed what. I immagine an onion ring model based on user consent and relationship constrain: user to seller, seller to manufacturer (original or oem), manufacturer (oem) to manufacturer Alex -Alessandro Festa website:http://alfweb.comtwitter:@festaatdellemail:afesta@alfweb.com Il Venerdì 24 Luglio 2015 13:10, Paul Madsen <pmadsen@pingidentity.com> ha scritto: Hi nat, I would follow on to your steps below On 7/24/15 4:56 AM, Nat Sakimura wrote: Yeah, it is nice, but WSDL would be too big. Remember that sending 1 byte over the radio takes as much power as encrypting 1000 bytes. Also, memory and processing power is becoming cheap, so in IoT context, we should probably treat "minimizing the radio packet" as the priority. As to the identification of the things are cocerned, the viable model that I imagine is as follows: - The device manufacutrer creates a good keypair and embeds the private key (and its key thumbprint) in the device. - For device authentication, use the key to sign the message. When acting on behalf of a user 3. Authenticated user facilitates delivery of tokens to device 4. Device authenticates to AS using embedded keys in order to obtain tokens 5. Device uses tokens to authenticate to cloud endpoints, other device etc Tokens thereby reflect 'relationship' of user & device Nat 2015-07-22 1:33 GMT+09:00 Aninda Bhunia <abhunia@inc38.com>: It would be interesting if we could create a standard that would allow even non IP devices to publish their identity through a wsdl type structure. Even if they are non IP at some point in their upwards relationship hierarchy their master gateway would be IP based and could be responsible for publishing the identity wsdls for the entities it brokers.

I believe Ingo has also noted this in the summaries from IDoT. Sal mentions NMAP / SNMP are there other exiting approaches?

In that case there are mechanisms support scanning ( eg NMAP) or SNMP that have been around for a while these are typically not exactly API friendly but do provide a starting point and we make good use in our offerings.

Just wanted to bounce a question which I’m consistently getting asked around Identity, IoT perspective. Is there any industry standard in place or in works which can be used as a common standard across multiple identities. What I mean by this is that humans have SSN as an identity while a thermostat may have serial number while a network device may have a Mac ID as their identity. So, while individually they all have their own identity standard, when in the IoT world, all these entities start interacting with each other, how do we translate one identity into another or how will one identity interact with another identity in a standards way?
