Securing Cloud-Based IoT Architectures: A Multi-Protocol Approach

Securing cloud-based IoT architectures has become a critical concern due to the increasing integration of heterogeneous IoT devices into cloud environments. Traditional security approaches often fall short in addressing the unique challenges posed by such architectures, including device diversity, real-time data processing, and scalability issues. This paper presents a novel multi-protocol security framework designed to enhance the protection of cloud-based IoT systems. By combining multiple security protocols, such as Transport Layer Security (TLS), Datagram Transport Layer Security (DTLS), and the Message Queuing Telemetry Transport (MQTT) protocol, the proposed approach provides a comprehensive defense against various security threats. The paper discusses the architecture and implementation of the multi-protocol model and evaluates its performance in terms of security, scalability, and resource efficiency. Comparative analysis with single-protocol solutions demonstrates the superiority of the multi-protocol approach in mitigating vulnerabilities across the cloud-IoT ecosystem. The proposed solution offers a scalable and adaptable method for ensuring secure communication and data integrity within cloud-based IoT architectures.
