Certificate-Less Healthcare Signature Scheme for Secure Consumer Technology-Centric Wireless Medical Sensor Devices

The application of Consumer-Centric Wireless Medical Sensor Devices in the medical field has brought great convenience to doctors and patients. However, the transmission process may compromise patient privacy, making the authenticity and integrity of medical data a significant challenge in the healthcare industry. To address this issue, a certificate-less Healthcare Signature scheme is proposed to protect patient privacy. However, most schemes are unable to resist fully selective cipher text attacks and suffer from key exposure problems. To mitigate these issues, a scheme is proposed to resist fully selective attacks in real-time processing of Consumer-Centric Wireless Medical Sensor Devices with high latency issues, while utilizing parallel key isolation methods to address key exposure problems. The scheme’s enforceability is proven based on the random oracle model and the computational Diffie-Hellman assumption, and its resistance to fully selective key attacks is proven based on hash-based collision resistance. It is shown that this plan works well for wireless sensor networks in the medical field. Sensor nodes have limited resources, and sending vast volumes of patient medical data online significantly raises processing and communication costs. The low processing power of edge devices limits the effectiveness and performance of medical services. Efficiency analysis using the MIRACL library demonstrates that the proposed scheme outperforms other relevant schemes in terms of efficiency at each stage, while also having lower communication overhead.
