Systems and methods used to securely communicate a shared key to devices. One embodiment describes a method to securely communicate a shared key to a first device (32) and a second device (34) that includes receiving (52), using the first device, a shared key and unique identifier pairing associated with the first device (32) from a key generator (36); receiving (54), using a trusted third party (38), the shared key and unique identifier pairing from the key generator (36); generating (80), using the first device (32), a signature using the unique identifier and the shared key; transmitting (82), using the first device (32), the signature and the unique identifier to the trusted third party (38); verifying (86), using the trusted third party (38), the unique identifier based on the signature; determining, using the trusted third party (38), the shared key when the unique identifier is verified; and transmitting (88), using the trusted third party (38), the shared key to the second device (34) to enable the first device (32) and the second device (34) to communicate securely by encoding and decoding communicated data using the shared key. |
