What is it ?
- brings Green Power device to ZigBee operating channel
- bootstraps Green Power device security
- creates a control relationship between the Green Power device and the sink
Designed for low power device
- No Rx
- No channel toggling
- Tx from energy harvesting
- …
A General Procedure
Uni-directional Commissioning
Designed for transmit only GPD
Bi-directional Commissioning: auto channel
Difference: How to get channel info ?
Bootstrap Security: the model
- Centralized
- Distributed
GP Security: distributed
- Sink decides if it accepts GPD
- Security level must meet minimum requirement
What is security level ?
The encryption: AES-CCM*
Encryption: test code
Decryption: test code
Different Encryption during GP commissioning: A re-look
Packet Trace Example
The GPD key is:
