Abstract
A method for pairing an accessory with a host device includes placing an output device of the accessory into a randomly selected state N-times. The information about the current state of the accessory is provided to a host device after each state selection for N number of times. Thereafter, the host device generates an authentication code based on the N inputs and the accessory generates another authentication code based on the N selected states. The authentication codes can be then compared and can be used to 'pair' the host device and the accessory, allowing secure communication.
