Hardware Security Chip Based on PUF Technology for Real-time Respiratory Disease Diagnosis System Protection

The rapid development of smart medical systems has significantly increased the importance of cybersecurity. If edge medical devices are compromised, patients’ private data could be stolen and used for improper purposes, and if the device identity is forged, it could lead to serious consequences. In this study, we proposed and applied a PUF-based secured smart healthcare system to the real-time respiratory disease diagnosis system. For this system, the PUF security chip is integrated and provides identity authentication, preventing the identity of edge devices from being forged. Additionally, all data transmission is encrypted, protecting patients’ private information. The PUF security technology ensures that no one can steal the security keys, making this a highly secure smart medical device.
