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.

医疗保健系统本质上是异构的，其中每个设备都在不同的体系结构，平台和操作系统上运行。这种异质性会在延迟和安全威胁方面影响通信性能。为了以很少的开销来管理密钥的目的，已经提出了一种优化的量子密钥管理技术，该技术通过减少威胁来增强医疗保健信息的安全性。并且还通过量子信道模拟了与关键权限的通信。生成的密钥通过专用的量子信道按量子比特进行分配，从而最大程度地降低了窃听率，传输错误和泄漏，从而进一步提高了安全性。医疗保健用户组和内容服务器通过发送光子的量子通道与密钥服务器通信。然后他们使用公共渠道讨论结果。在通过量子通道从密钥服务器获得加密密钥后，内容服务器可以对其医疗内容进行加密，并通过任何公共渠道将其发送给医疗用户组。这项拟议的研究工作调查了不同类型的医疗保健网络的组密钥生成问题，并解决了量子密钥分配问题，从而增强了医疗保健网络中的密钥安全性。分析表明，这两种算法在医疗网络中都能产生最佳的组密钥率。还提供了数值结果，以验证所提出的密钥生成，优化和量子分布的性能。密钥生成
