A method of fitting a hearing device, comprising: initiating a fitting session by initiating pairing between a first fitting station and the hearing device, each of the hearing device and the first fitting station having a wireless communication interface using a communication protocol; providing a long-term key (LTK) as a shared secret to the first fitting station and the hearing device, the LTK being suitable for establishing a secure connection between the first fitting station and the hearing device via the communication interfaces; generating an identity resolving key (IRK) of the first fitting station, which is required for generating and resolving a device address of the first fitting station; providing the IRK of the first fitting station to the hearing device; providing an IRK of the hearing device, which is required for generating and resolving a device address of the hearing device, to the first fitting station; storing pairing data including the LTK, the IRK of the fitting station and the IRK of the hearing device, together with an association between the first fitting station and the hearing device, in a database connected to the first fitting station; storing the LTK and the IRK of the fitting station in the hearing device; conducting a fitting session via a secure connection between the first fitting station and the hearing device via the wireless communication interfaces; and disconnecting the first fitting station and the hearing device. Claim: 2. The method of claim 1, wherein the protocol is Bluetooth LE. Claim: 3. The method of claim 2, wherein the device address of the hearing device is a random resolvable address. Claim: 4. The method of claim 3, wherein the device address of the hearing device is generated by passing the IRK of the hearing device to the Bluetooth LE “initialize” function. Claim: 5. The method of claim 2, wherein the device address of the first fitting station is a random resolvable address. Claim: 6. The method of claim 2, wherein the public Bluetooth addresses of the first fitting station and the hearing device are exchanged between the first fitting station and the hearing device during pairing. Claim: 7. The method of claim 1, wherein the IRK of the hearing device is provided to the hearing device out-of-band. Claim: 8. The method of claim 7, wherein the IRK of the hearing device is provided to the hearing device during manufacturing. Claim: 9. The method of claim 7, wherein the IRK of the hearing device is provided from the hearing device to the first fitting station via a secure connection between the wireless interfaces. Claim: 10. The method of claim 1, wherein the IRK of the first fitting station is generated by the first fitting station utilizing a random number generator. Claim: 11. The method of claim 1, wherein the IRK of the first fitting station is provided from the first fitting station to the hearing device via a secure connection between the wireless interfaces. Claim: 12. The method of claim 1, wherein the first fitting station identifies itself as a fitting station to the hearing device prior to pairing, and wherein the IRK of the first fitting station and the LTK are stored in a special location of the pairing table of the hearing device reserved for fitting stations. Claim: 13. The method of claim 1, wherein an association between the hearing device and a certain user is stored in the database. Claim: 14. The method of claim 1, wherein pairing between the first fitting station and the hearing device is initiated by a user gesture on the first fitting station and the hearing device. Claim: 15. The method of claim 1, wherein the LTK is generated during pairing. Claim: 16. The method of claim 1, wherein the method further comprises initiating a follow-up fitting session on a second fitting station comprising a wireless communication interface using said communication protocol by: connecting the second fitting station to the database; retrieving, by the second fitting station, the pairing data from the database; generating, in the second fitting station, a device address of the second fitting station by using the IRK of the first fitting station, and generating, in the hearing device, a device address by using the IRK of the hearing device; exchanging the device addresses between the second fitting station and the hearing device; resolving, in the second fitting station, the device address received from the hearing device by using the IRK of the hearing device, and resolving, in the hearing device, the device address received from the second fitting station by using the IRK of the second fitting station; connecting the second fitting station and the hearing device via the communication interfaces by using the retrieved pairing information and the resolved device addresses; conducting a follow-up fitting session via a secure connection between the second fitting station and the hearing device via the wireless communication interfaces; and disconnecting the second fitting station and the hearing device. Claim: 17. The method of claim 1, wherein the first fitting station comprises a PC and a fitting device connected to the PC and comprising the wireless interface. Claim: 18. A non-transitory computer-readable medium storing a computer program that, when executed, direct a processor to: initiate a fitting session by initiating pairing between a first fitting station and the hearing device, each of the hearing device and the first fitting station having a wireless communication interface using a communication protocol; provide a long-term key (LTK) as a shared secret to the first fitting station and the hearing device, the LTK being suitable for establishing a secure connection between the first fitting station and the hearing device via the communication interfaces; generate an identity resolving key (IRK) of the first fitting station, which is required for generating and resolving a device address of the first fitting station; provide the IRK of the first fitting station to the hearing device; provide an IRK of the hearing device, which is required for generating and resolving a device address of the hearing device, to the first fitting station; store pairing data including the LTK, the IRK of the fitting station and the IRK of the hearing device, together with an association between the first fitting station and the hearing device, in a database connected to the first fitting station; store the LTK and the IRK of the fitting station in the hearing device; conduct a fitting session via a secure connection between the first fitting station and the hearing device via the wireless communication interfaces; and disconnect the first fitting station and the hearing device.
