IoT in Healthcare: A Secure Way to Monitor Patients

IoT devices are small sensors that can do big things. They are used in many areas, like e-Health, smart cities, and assisted living. These devices have limited power, memory, and computing capabilities. This makes security a big challenge. One area where IoT is making a big impact is healthcare. The goal is to automate the monitoring of hospitals and patients' health. This can help reduce the strain on hospitals and make medical responses faster. A new system uses IoT devices and the MQTT protocol to monitor patients remotely. This system uses one-time pad cryptography to ensure data secrecy. This means that the message is encrypted on both the publisher and subscriber ends before it is sent through the MQTT protocol. The system is designed to be lightweight and efficient. It has low computational overhead compared to other solutions that use conventional encryption. This makes it more secure against most IoT security attacks. The system also manages patients' movements inside nursing homes and healthcare facilities safely. It does not require periodic reconfigurations. This makes it a reliable and convenient option for remote patient monitoring. The proposed scheme is more efficient than delegation-based architecture in terms of security and lightweight communication. This makes it a promising solution for the future of healthcare.
