Abstract

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.
