A Comparative Analysis of IoT Security Frameworks With BIoTC

The Internet of Things (IoT) has reshaped the modern intelligent environments, but it remains vulnerable to sophisticated attacks such as Man-in-the-Middle (MITM), RFID cloning, unauthorized access, and social engineering. Block Internet of Things Chain (BIoTC) introduces a simulation-based approach to address these security issues.  While various frameworks have been proposed to secure IoT systems, most of them fall short in practical validation or comprehensive protection. This paper presents a comparative analysis of existing IoT security frameworks against a proposed solution named the Blockchain Internet of Things Chain (BIoTC). A Cisco Packet Tracer simulated smart home environment is used to construct the framework’s architecture. This framework also consists of a lightweight blockchain infrastructure. This lightweight module uses smart contract- like policy logic. The logic is implemented at Python blockchain layer for access validation and includes rule-based anomaly detection. In this research work, the BIoTC discloses its ability to detect and address security issues.in simulated smart home environment. This is done by dividing the solution into different subparts. These subparts or modules mimic several issues like different attacks, anomaly detection and device verification. The findings indicates that the framework demonstrates adaptability, qualitative detection effectiveness, and visual feedback. The result indicates that the framework is suitable option for protecting smart home devices in simulated environments. This research work demonstrates that the blockchain based validation can effectively support IoT security in simulation driven environments.
