A method for transmitting end-to-end encrypted super group information, the method comprising: transmitting temporary address data, which identifies a temporary address used for a super group, from a gateway to a back-to-back communications device, the gateway providing a connection between the back-to-back communications device and a trunked switching and management infrastructure, wherein the super group encompasses a plurality of talk groups, wherein the back-to-back communication device is a wireless communication device that is capable of communicating with another wireless communication device without using an infrastructure, wherein the temporary address data identifies a frequency or channel used for the super group, and wherein the back-to-back communication device is a member of a talk group of the plurality of talk groups having a talk group address different from the temporary address data; retrieving from storage in the back-to-back communications device an encryption key associated with the temporary address, wherein the talk group address is associated with an encryption key different from the encryption key associated with the temporary address data; replacing, by the back-to-back communications device, the talk group address and associated encryption key with the temporary address and associated encryption key for a super group communication; decrypting encrypted super group information at the back-to-back communications device using the encryption key retrieved from storage to permit end-to-end encryption of the super group information, wherein super group information is any type of data that may be exchanged among wireless communication devices that are part of a super group; and reverting, by the back-to-back communications device, back to the talk group address and associated encryption key from the temporary address and associated encryption key in response to termination of the super group communication. transmitting temporary address data, which identifies a temporary address used for a super group, from a gateway to a back-to-back communications device, the gateway providing a connection between the back-to-back communications device and a trunked switching and management infrastructure, wherein the super group encompasses a plurality of talk groups, wherein the back-to-back communication device is a wireless communication device that is capable of communicating with another wireless communication device without using an infrastructure, wherein the temporary address data identifies a frequency or channel used for the super group, and wherein the back-to-back communication device is a member of a talk group of the plurality of talk groups having a talk group address different from the temporary address data; retrieving from storage in the back-to-back communications device an encryption key associated with the temporary address, wherein the talk group address is associated with an encryption key different from the encryption key associated with the temporary address data; replacing, by the back-to-back communications device, the talk group address and associated encryption key with the temporary address and associated encryption key for a super group communication; decrypting encrypted super group information at the back-to-back communications device using the encryption key retrieved from storage to permit end-to-end encryption of the super group information, wherein super group information is any type of data that may be exchanged among wireless communication devices that are part of a super group; and reverting, by the back-to-back communications device, back to the talk group address and associated encryption key from the temporary address and associated encryption key in response to termination of the super group communication.
