    Abstract: Disclosed herein, among other things, are systems and methods for authentication and encryption key exchange with an ALD for hearing device applications. A method includes receiving an acoustic input at a microphone of a hearing device, and receiving a wireless signal over a wireless link from an assistive listening device (ALD) at an antenna of the hearing device, the wireless signal including digital audio information. The acoustic input is compared to the digital audio information using a processor of the hearing device. Upon determining that the acoustic input and the digital audio information are correlated at a threshold level, the processor is used to create and distribute an encryption key to the ALD to secure the wireless link. The ALD may include a processor for correlating the input and the information, and for creating and distributing the encryption key, in some embodiments.
