Claim 18:
19. A non-transitory computer-readable storage medium, the computer-readable storage medium including instructions that, when executed by a computer, cause the computer to:
receive device advertised data comprising a time-dependent device identifier generated at the device using a time-dependent data calculation, a shared master secret and time data comprising current time data and reference time data, the shared master secret and the reference time data shared between the device and a control system;
generate augmented data comprising:
a hashed device identifier generated by hashing the time-dependent device identifier using a hash function known to both the intermediary system and the control system; and
an encrypted message generated by encrypting a message using the time-dependent device identifier as an encryption key for a symmetric encryption/decryption method known to both an intermediary system and the control system; and

provide the augmented data for retrieval and processing by the control system to allow the control system to communicate with the device securely.
