Enhance the Internet of Things Light Weight Communication System Protocol Authentication

Currently, Internet of Things (IoT) technology based on smart homes has been created and used extensively.Applications include remote or automated control of electrical appliances and electronics, where users can utilize smart devices to transmit commands to an IoT device or device gateway.Security and authentication procedures for Internet of Things devices have been the subject of innumerable research papers in recent years.The power limitations of IoT devices are still not taken into account, though.A security and authentication system that uses fewer hash functions and encryption techniques is presented in their study.The result is that it uses less power when communicating and so conforms with IoT and mobile device power limitations.The secure and compact communication protocol for the Internet of Things is still challenging to guarantee secure connections for Internet of Things (IoT) technologies.Deploying communication strategies based on asymmetric cryptographic systems might be challenging in IoT environments because of the strict resource restrictions of computing, memory, and communication.Using symmetric encryption techniques based on pre-shared keys is an alternative.The lightweight key synchronization update mechanism that is presented in the paper serves as a foundation for our suggested lightweight secure communication protocol.Analysis of the protocol's Security demonstrates that it is resilient to common attacks like replay and man-in-themiddle attacks.For formal verification, we next employ a commonly used Security protocol verification tool.Furthermore, consider the lightweight key synchronization update algorithm's computational efficiency and unpredictability and show that it performs better than alternative systems.To prove usefulness, they additionally consider the protocol's performance in terms of communication and computation expenses.
