Secure wireless network setup using multicast packets

A non-transitory tangible computer readable medium storing a computer program executable on a processor of an apparatus, the computer program comprising:

• instructions for retrieving a packet of data from a wireless access point, wherein the packet includes (i) a destination address and (ii) a payload, wherein the destination address is a multicast media access control (MAC) address, and wherein the multicast MAC address includes at least a portion of an encrypted wireless network security string;
• instructions for decrypting the encrypted wireless network security string using a device key of the apparatus;
• instructions for producing a wireless network security key based on the decrypted wireless network security string;
• and
• instructions for decrypting payloads of packets from the wireless access point using the wireless network security key.

An apparatus comprising:

• an input module configured to receive
• (i) a wireless network security string for a wireless local area network established by a wireless access point, and
• (ii) a device key of a device attempting to join the wireless local area network;
• a processor configured to encrypt the wireless network security string with the device key;
• and
• a transmitter configured to transmit a packet to the device via the wireless access point, wherein
• the packet includes (i) a destination address and (ii) a payload,
• the destination address is a multicast media access control (MAC) address, and
• the multicast MAC address includes at least a portion of the encrypted wireless network security string.
