Abstract

The present invention relates to client devices with certificates and related methods. The client device comprises a processing unit, a memory unit having a client device key and a client device certificate stored thereon, and an interface, wherein the processing unit is configured to: receive a connection response comprising the hearing device identifier via the interface ; Generate one or more keys, including a certificate key, based on the hearing device identifier and the client device key; obtain a verification message based on the certificate key and the client device certificate, wherein obtaining the verification message includes: encrypting the client device certificate, generating an encrypted client device certificate, and including the encrypted client device certificate in an authentication message; and sending the authentication message via the interface.

Description

technical field [0001] The present disclosure relates to a client device and related method for hearing device communication. In particular, a method of operating a client device for hearing device communication is disclosed. Background technique [0002] The capabilities of hearing devices are becoming more and more advanced. Wireless communication between hearing devices and external devices such as hearing device fittings, tablets, smartphones and remote controls has been developed. The wireless communication interface of the hearing device uses an open, standards-based interface. However, this poses many challenges in terms of security. The hearing device may assume that any input data is legitimate and may cause the memory to be written or changed by unauthorized parties. Any such attack could result in malfunctioning of the hearing aid or a battery drain attack. Contents of the invention [0003] There is a need for a client device and method that provides impro...
