Secure data communication method for medical devices via bluetooth
The patent US12047417B2 outlines a method for establishing a secure data communication link between a medical apparatus and a data management device, both equipped with Bluetooth technology. The process begins with an out-of-band transmission of a public key and device information from the medical apparatus to the data management device, which does not occur via Bluetooth. Following this, an encrypted Bluetooth link is established based on the Just Works principle, allowing for the secure exchange of public keys between the devices. Each device then calculates a combined key using their respective secret keys and the received public keys, ultimately setting up an end-to-end encrypted communication link for data transmission.
Additionally, the patent describes various methods for the out-of-band transmission of the public key, including near field communication and optical detection using a camera. The medical apparatus can dynamically generate key pairs and may include features such as a display for presenting the public key in graphic formats like QR codes. The system is designed to facilitate secure data exchange between various medical devices, such as insulin injection devices and blood glucose meters, and a data management device, typically a smartphone. The claims emphasize the importance of encryption and secure communication in managing physiological data, ensuring that sensitive information is protected throughout the data exchange process.
