Abstract:
A controller and an accessory controllable by the controller can communicate using secure read and write procedures. The procedures can include encrypting identifiers of accessory characteristics targeted by a read or write operation as well as any data being read or written. The procedures can also include the accessory returning a cryptographically signed response verifying receipt and execution of the read or write instruction. In some instances, a write procedure can be implemented as a timed write in which a first instruction containing the write data is sent separately from a second instruction to execute the write operation; the accessory can disregard the write data if the second instruction is not received within a timeout period after receiving the first instruction.

Claim (Index 9):
A computer-readable storage medium having stored therein program code that, when executed by one or more processors of a controller, cause the one or more processors to perform operations comprising:\n determining that a new verified session with an accessory is to be established, the new verified session based at least in part on a previously verified session with the accessory; receiving a saved session identifier and a saved shared secret corresponding to the previously verified session with the accessory; generating a pair resume request, the pair resume request including the saved session identifier; transmitting the pair resume request to the accessory; receiving a pair resume response from the accessory, the pair resume response including a second session identifier; determining a second shared secret based at least in part on the second session identifier; and based at least in part on the second shared secret corresponding to the saved shared secret, establishing the new verified session with the accessory using the second session identifier.
