Communication method and device for implantable medical system

Abstract

The invention discloses a communication method and equipment for an implantable medical system, wherein a communication method includes receiving encrypted identification information sent by the implanted equipment; using a first password to perform encryption on the encrypted identification information Decryption; establish a wireless connection with the implant device after successful decryption; send a second password to the implant device; receive data encrypted by a third password fed back by the implant device according to the second password, and The data is decrypted using the third cipher. The method and the device provided by the invention enable data communication between the external device and the implanted device through triple password to improve the security of the wireless communication.

Description

technical field [0001] This application relates to the field of communication security, in particular to a communication method and device for an implantable medical system. Background technique [0002] Implantable Medical Device (IMD) is a medical device installed inside the user's body. This device has batteries, chips, and sensors inside, and relies on set programs and operating parameters to achieve corresponding treatments. [0003] Implantable medical devices usually include two parts, the device implanted in the body and the control device outside the body, and data needs to be transmitted between the two to control various functions of the device. Most of the existing IMDs use a communication method based on electromagnetic pulse position modulation (PPM) to enable wireless communication between devices implanted in the body and external control devices. This method has low communication efficiency, poor anti-interference ability, short communication distance, and h...

Problems solved by technology

Most of the existing IMDs use a communication method based on electromagnetic pulse position modulation (PPM) to enable wireless communication between devices implanted in the body and external control devices. This method has low communication efficiency, poor anti-interference ability, short communication distance, and high reliability. lower

Using communication technologies such as Bluetooth and WiFi can greatly improve the communication efficiency and communication distance of IMD. However, existing wireless communication technologies such as Bluetooth and WiFi use open protocols. When devices implanted in the body broadcast beacons to the outside, it will cause Any external device has the possibility to connect to the device implanted in the body. It can be seen that the security of this communication method cannot meet the needs of implanted medical systems, and there are potential safety hazards
