Method of fitting a hearing assistance device

A method for conducting a fitting session, the method comprising:

• generating, separately from a hearing device and a fitting station, a production key;
• distributing out-of-band the production key to both the fitting station and the hearing device;
• initiating, via the fitting station, a connection to the hearing device to establish a non-encrypted connection between the fitting station and the hearing device;
• using the production key in both the fitting station and the hearing device to pair the fitting station and the hearing device to establish a secure connection between the fitting station and the hearing device, wherein the secured connection includes encrypted communication based at least in part on a shared secret;
• and
• conducting a fitting session via the secure connection between the fitting station and the hearing device.

• generating, separately from a hearing device and a fitting station, a production key;
• distributing out-of-band the production key to both the fitting station and the hearing device, and storing the production key on both the fitting station and the hearing device;
• initiating, via the fitting station, a connection to the hearing device to establish a non-encrypted connection between the fitting station and the hearing device;
• using the production key in both the fitting station and the hearing to pair the fitting station and the hearing device to establish a secure connection between the fitting station and the hearing device wherein the secured connection includes encrypted communication based at least in part on the production key;
