Improving security in the 5G-based medical Internet of Things to improve the quality of patient services

The Internet of Medical Things (IoMT) is like a tech upgrade that benefits patients by reducing healthcare costs, making medical care more accessible, and improving the quality of treatment. To make IoMT devices smart and capable, they need super-fast 5G support. However, there are security concerns when using IoMT devices that can put a patient's data and privacy at risk. For instance, someone could eavesdrop on your medical data due to weak network access management and data encryption. Many systems use encryption methods to protect data, but these methods often fall short when it comes to the high security standards required for healthcare data and patient service quality. In our research, we introduce a new solution called the Hybrid MD5 and Threefish Encryption (HMTE) to make IoMT more secure and improve the quality of care for patients. To ensure efficient use of energy, we employ a smart approach when choosing a cluster head. When it comes to sending data, we use the Trust-Based Energy Efficient Routing Protocol (TEERP). We carefully evaluate different aspects like cost, encryption and decryption speed, and the level of security while analyzing our proposed method. We also compare our solution with existing methods. Our data shows that our recommended solution outperforms existing methods, particularly in terms of enhancing security to improve the quality of care for patients. © 2024 College of Education, Al-Iraqia University.
