摘要

Medical Internet of things (MIoT) devices are enabling smart health care by collecting huge amounts of real-time, sensitive patient data. Consequently, these smart systems become prime targets for sophisticated cyberattacks. As hacking incidents occur frequently, it is necessary to have fast and powerful computing to keep healthcare data secure. The proposed Ascon with quantum key distribution (AQKD) framework has sophisticated computational technologies with robust encryption keys. If there is not enough computing power, these security checks can slow down or fail, threatening patient safety and privacy. To keep up with the rapid flow of real-time health data, the AQKD system secures MIoT devices and checks their integrity multiple times in microseconds. The proposed framework can execute several tasks concurrently, thus satisfying the requirements for high-performance computing and real-time processing. The experimental evaluation indicates that the proposed AQKD generates 128-bit keys in 0.0023 ms. For higher key sizes, the observed key generation time is lower than that of Kyber and Falcon under similar settings. The framework supports a total key generation rate of up to 475,000 keys per second, with an average key generation time of about 21.05 µs per medical IoT node. The modified Hash verification system withstands various cyberattacks (fake messages, data theft, impersonation, etc.). AQKD maintains fast operation and secure MIoT systems with limited computing resources. Thus, it emphasizes the system’s ability to handle demanding security tasks efficiently in both resource-rich and resource-constrained environments.
