## Abstract

A method performed by a fitting device, the fitting device being a part of a hearing system configured for remotely configuring a hearing device, the method includes: obtaining hearing device data comprising a hearing device identifier of the hearing device; obtaining a session key; generating a configuration initiation request based on the session key and the hearing device identifier; transmitting the configuration initiation request to a server device; receiving a configuration initiation response from the server device, the configuration initiation response comprising configuration keying material; generating a configuration package based on configuration data for the hearing device and based on the configuration keying material, the configuration package comprising configuration package data; and transmitting the configuration package to the server device.

## Claims

### Claim 1

A method performed by a fitting device, the fitting device being a part of a hearing system configured for remotely configuring a hearing device, the method comprising:
obtaining hearing device data comprising a hearing device identifier of the hearing device;
obtaining a session key;
generating a configuration initiation request based on the session key and the hearing device identifier;
transmitting the configuration initiation request to a server device;
receiving a configuration initiation response from the server device, the configuration initiation response comprising configuration keying material;
generating a configuration package based on configuration data for the hearing device and based on the configuration keying material, the configuration package comprising configuration package data; and
transmitting the configuration package to the server device.

### Claim 2 (depends on 1)

The method according to claim 1, wherein the act of generating the configuration initiation request comprises encrypting the session key using a configuration initiation public key, and including the encrypted session key in the configuration initiation request.

### Claim 3 (depends on 1)

The method according to claim 1, wherein the hearing device data comprises a shared index, a fitting device key identifier, an address identifier, fitting information, or any combination of the foregoing.

### Claim 4 (depends on 1)

The method according to claim 1, wherein the configuration keying material is encrypted, and wherein the method further comprises decrypting the configuration keying material.

### Claim 5 (depends on 1)

The method according to claim 1, wherein the act of generating the configuration package comprises obtaining a configuration data integrity indicator, and wherein the configuration package data is based on the configuration data integrity indicator.

### Claim 6 (depends on 1)

The method according to according to claim 1, wherein the act of generating the configuration package comprises encrypting the configuration data and/or configuration data integrity indicator.

### Claim 7 (depends on 6)

The method according to claim 6, wherein the configuration package data comprises a configuration payload block, and wherein the configuration payload block comprises the encrypted configuration data and/or the encrypted configuration data integrity indicator.

### Claim 8 (depends on 7)

The method according to claim 7, wherein the configuration package data also comprises a control block.

### Claim 9 (depends on 6)

The method according to claim 6, wherein the configuration data and/or the configuration data integrity indicator is encrypted using the configuration keying material.

### Claim 10 (depends on 1)

The method according to claim 1, wherein the act of generating the configuration package comprises encrypting the configuration package data.

### Claim 11 (depends on 1)

The method according to claim 1, further comprising:
sending an access request to the server device; and
receiving an access response from the server device.

### Claim 12 (depends on 1)

The method according to claim 1, further comprising deleting the session key and the configuration keying material after the configuration package is transmitted.

### Claim 13 (depends on 1)

A fitting device configured to perform the method of claim 1.
