I am working on Zigbee security. For key establishment, some approaches are given in Zigbee. Some of them are:
- ASKE (Alpha Secure Key Establishment),
- ASAC (Alpha Secure Access Control), and
- SKKE (Symmetric Key Key Establishment).
I tried to do my own research, but didn't get proper information on the web. I would like to know what these mechanisms are, and how do they establish a key between two devices?
At least, where can I get the information about these mechanisms?
