Challenges

• Ease of commissioning• Ease of reconfiguration• Provisioning of keys / Device Authentication– IEEE 802.15.9 KMP transport

• Rekeying• Cost• Sleeping and Energy Harvesting devices

Questions

• What is an appropriate level of security?• What techniques provide security with

smallest impact (data, code, bandwidth) ?• Is privacy a concern?• How many engineers does it take to change a

light bulb?
