Joel, you have gotten the resale problem exactly correct. BRSKI is primarily a protocol for a buyer, who does not wish to be forced to assert physical possession, to assert ownership of the device. The #1 reason why they don't want to resort to physical means is that the local entities possessing ("remote hands") the device don't have the skills and/or equipment to set the device up. The #2 reason is that the device is in partial public access, and it would be a bad thing if the physical possession interface was too easily accessed. (Bank ATM, Airport checkin kiosk, hotel room interfaces, etc.) This has been extended to IoT devices. A third reason is that the devices may be difficult to actually reach physically due to the structure and activity of the factory/plant/etc. that they are in. A temperature sensor 50m up a distillation tower in a refinery, for instance. The physical mechanisms that make the device hard to physically attack may also make it hard for the second owner to take control of the device without the cooperation of the first owners and/or manufacturer. The current solution in the document is that one should, for enterprise/ISP equipment that ANIMA applies to, continue to provide the same onboarding processes that existed prior to ANIMA. Specifically, a "craft" or serial console. -- ] Never tell me the odds! | ipv6 mesh networks [ ] Michael Richardson, Sandelman Software Works | IoT architect [ ] mcr@sandelman.ca http://www.sandelman.ca/ | ruby on rails [ -- Michael Richardson <mcr+IETF@sandelman.ca>, Sandelman Software Works -= IPv6 IoT consulting =-
