The present disclosure relates to establishing secure communication between a dialysis machine and medical equipment. In an example, a dialysis machine includes a control unit configured to establish a short-range wireless connection with external medical equipment. The control unit establishes the short-range wireless connection by causing a user interface to display a prompt to enter a passkey associated with medical equipment, using the received passkey to pair with the medical equipment, and creating a new bonding table or writing to an empty bonding table using the passkey. The control unit is also configured to generate a shared key using the passkey and at least one predetermined criterion and use the shared key to authenticate with the medical equipment. When authentication with the medical equipment is successful, the control unit enables data communication using the short-range connection with the medical equipment.

Dialysis machine, medical equipment, and methods for establishing secure communication between a dialysis machine and medical equipment

The present disclosure relates to establishing secure communication between a dialysis machine and a fluid preparation device. In an example, a dialysis machine includes a control unit configured to establish a short-range wireless connection with an external fluid preparation device. The control unit establishes the short-range wireless connection by causing a user interface to display a prompt to enter a passkey associated with a fluid preparation device, using the received passkey to pair with the fluid preparation device, and creating a new bonding table or write to an empty bonding table using the passkey. The control unit is also configured to generate a shared key using the passkey and at least one predetermined criterion and use the shared key to authenticate with the fluid preparation device. When authentication with the fluid preparation device is successful, the control unit enables data communication using the short-range connection with the fluid preparation device.

Dialysis machine, a fluid preparation device, and methods for establishing secure communication between a dialysis machine and a fluid preparation device

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.

Dialysis machine, external medical equipment and methods for establishing secure communication between a dialysis machine and external medical equipment

A method and apparatus are provided for initial certification enrollment in a wireless communication system. A first mobile device establishes a first wireless connection with an infrastructure and a second wireless connection with a second mobile device. The first mobile device receives, from the second mobile device, a first certification request that includes a request for a digital certificate for the second mobile device and first biometric data associated with a user of the first mobile device. The first mobile device obtains second biometric data associated with a user of the second mobile device and conveys a second certification request to the infrastructure that includes the request for the digital certificate for the second mobile device and the first and second biometric data. The first mobile device then receives, from the infrastructure, the digital certificate for the second mobile device and forwards, to the second mobile device, the digital certificate.
