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 (mine not yours)
• 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?
