Systems and methods for communication in a wireless network are disclosed. In one aspect, a method includes generating a medium access control (MAC) address for a first group of wireless devices, storing the MAC address for the first group of wireless devices in an address field of a first message, and transmitting, by a first wireless device of the first group of wireless devices, the first message to a second wireless device of the first group of wireless devices. In some aspects, the wireless network comprises a neighbor aware network (NAN). In some aspects, a wireless device may be able to determine a method of encryption or decryption for the first message based at least in part on the MAC address for the first group of wireless devices.
