Abstract

An apparatus, e.g. a wireless media access point, includes a transceiver, a non-transitory storage medium, and a processor operably coupled to the transceiver and the storage medium. The processor is configured by instructions stored on the storage medium to transmit a first multicast channel associated with a first group temporal key (GTK), and to simultaneously transmit a second multicast channel associated with a second GTK.

1 . An apparatus, comprising:
 a transceiver;   a non-transitory storage medium; and   a processor operably coupled to the transceiver and the storage medium, the processor being configured by instructions stored on the storage medium to transmit a first multicast channel associated with a first group temporal key (GTK), and to simultaneously transmit a second multicast channel associated with a second GTK.   
     
     
         2 . The apparatus of  claim 1 , wherein the processor is further configured to associate the first GTK with the first multicast channel in a first GTK exchange message, and to associate the second GTK with the second multicast channel in a second GTK exchange message. 
     
     
         3 . The apparatus of  claim 1 , wherein the processor is further configured to simultaneously direct the first multicast channel encrypted with said first GTK to a first client device and the second multicast channel encrypted with said second GTK to a second client device. 
     
     
         4 . The apparatus of  claim 1 , wherein the processor is further configured to provide the first GTK to a first client device in response to receiving a first request from the first client device to join the first multicast channel, and to provide, without modifying the first GTK, the second GTK to a second client device in response to receiving a second request from the second client device to join the second multicast channel. 
     
     
         5 . The apparatus of  claim 4 , wherein the processor is further configured to provide a third GTK to the first client device and a fourth GTK to the second client device in response to receiving a request from the first client device to join a third multicast channel. 
     
     
         6 . The apparatus of  claim 1 , wherein the processor is further configured to implement an 802.11 communication standard. 
     
     
         7 - 9 . (canceled) 
     
     
         10 . A method performed at a media access point, comprising:
 transmitting a first multicast channel associated with a first group temporal key (GTK); and   simultaneously transmitting device a second multicast channel associated with a second GTK.   
     
     
         11 . The method of  claim 10 , further comprising directing to a first client device a first GTK exchange message that associates the first GTK with the first multicast channel, and directing to a second client device a second GTK exchange message that associates the second GTK with the second multicast channel. 
     
     
         12 . The method of  claim 10 , further comprising simultaneously directing the first multicast channel to a first client device and directing the second multicast channel to a second client device. 
     
     
         13 . The method of  claim 10 , further comprising directing the first GTK to a first client device in response to receiving a first request from the first client device to join the first multicast channel, and directing the second GTK to a second client device in response to receiving a second request from the second client device to join the second multicast channel. 
     
     
         14 . The method of  claim 13 , further comprising directing a third GTK to the first client device and a fourth GTK to the second client device in response to receiving a request from the first client device to join a third multicast channel. 
     
     
         15 - 16 . (canceled) 
     
     
         17 . A method, comprising:
 configuring a processor to transmit a first multicast channel associated with a first group temporal key (GTK); and   configuring the processor to simultaneously transmit a second multicast channel associated with a second GTK.   
     
     
         18 . The method of  claim 17 , further comprising configuring the processor to simultaneously direct the first multicast channel to a first client device and the second multicast channel to a second client device. 
     
     
         19 . The method of  claim 17 , further comprising configuring the processor to provide the first GTK to a first client device in response to receiving a first request from the first client device to join the first multicast channel, and to provide the second GTK to a second client device in response to receiving a second request from the second client device to join the second multicast channel. 
     
     
         20 . The method of  claim 19 , further comprising configuring the processor to provide a third GTK to the first client device and a fourth GTK to the second client device in response to receiving a request from the first client device to join a third multicast channel. 
     
     
         21 - 22 . (canceled)
