Abstract
The present disclosure relates to a dialysis machine, external medical equipment and to methods for establishing an authenticated connection between a dialysis machine and external medical equipment. The dialysis machine is caused to establish a short-range wireless connection between the dialysis machine and external medical equipment. A first shared key is associated with the short-range wireless connection. The dialysis machine is further configured to obtain a second shared key generated using the first shared key and to generate a first signature, using the obtained second shared key. The dialysis machine is further configured to send, to the external medical equipment, an authentication request comprising the generated first signature and to receive in return an authentication accept comprising a second signature. Furthermore, the dialysis machine is configured to verify the authenticity of the external medical equipment using the second signature.
