SECURE DISTRIBUTION OF A COMMON NETWORK KEY IN A WIRELESS NETWORK

摘要

Methods, devices, and systems are described to enable generating and securely distributing a common network key in a wireless network. For example, instead of each station of the wireless network generating a station-specific group network key, a particular station may generate and securely transmit a common network key to be used by multiple stations in the wireless network to decrypt group messages from multiple stations in the wireless network.
