Authentication of medical device computing system by using metadata signatures

Abstract

A computer code embedded in an electronic component (e.g., a processor, a sensor, etc.) of a medical device, such as a dialysis machine, may be authenticated by comparing a metadata signature derived from the computer code of the electronic component with a key derived from a pre-authentication code associated with the electronic component. The metadata signature may be derived by running an error check / error correction algorithm (e.g., SHA256) on computer code of the electronic component. The use of the metadata signature enables detection of any unauthorized changes to the computer code as compared to the pre-authenticated code.

Description

technical field [0001] The present invention relates to authentication of electronic components of computing systems, such as computing systems of medical devices. Background technique [0002] Data security is of paramount importance in computing systems. This is especially true for medical devices such as dialysis machines including peritoneal dialysis machines and hemodialysis machines. Official bodies such as the US Food and Drug Administration (FDA: Food and Drug Administration) require a high level of cybersecurity for medical and drug delivery devices. Unauthorized manipulation of the code of such medical devices could seriously compromise the data security of these devices. Contents of the invention [0003] Embodiments of the present disclosure include computer-implemented methods for verifying and authenticating computer systems including multiple programmable subsystems (eg, PCBs) and / or electronic components (eg, processors, sensors, FPGAs, etc.). For exampl...
