Architectural framework and simulation of quantum key optimization techniques in healthcare networks for data security

摘要

Healthcare systems are heterogeneous by nature, where each device is running on different architectures, platform and operating system. This heterogeneity affects the communication performance in-terms of delay and security threats. An optimized quantum key management technique has been proposed for the purpose of managing the keys with little overhead, which enhances the health care information security by reducing the threats. And also the communication with the key authority is simulated with the quantum channel. The generated key is distributed via a dedicated quantum channel in terms of quantum bits which decreases the eavesdropping rate, transmission error, and leakage to maximum extent which improves the security further. Healthcare User group and content server communicate with the key server via a quantum channel sending them photons. Then they discuss results using a public channel. After getting an encryption key from the key server via the quantum channel, the content server can encrypt their healthcare content and send them by any public channel to the healthcare user groups. This proposed research work investigates group secret key generation problems for different types of Healthcare networks and also addresses the quantum key distribution which enhances the key security in healthcare networks. The analysis shows that the two algorithms yield optimal group key rates in healthcare networks. Numerical results are also provided to validate the performance of the proposed key generation, optimization and quantum distribution. The key generation, optimization and healthcare content encryption and decryption using those keys enhances the security of patient data and quantum simulation shows that about 90% of eavesdropping rate is reduced in healthcare network.
