Abstract :
The rise of the Internet of Things (IoT) has significantly increased the generation of sensitive and continuous sensor data, which poses significant security challenges when transmitted to the cloud. Cloud computing provides scalable storage and real-time processing solutions for such data but introduces concerns related to unauthorized access, data breaches, and system vulnerabilities. This paper proposes a comprehensive security framework that ensures the confidentiality, integrity, and availability of IoT sensor data throughout its lifecycle. The framework integrates data pre-processing, AES encryption, Intrusion Detection Systems (IDS), secure transmission, and access control mechanisms to build a robust defence against cyber threats, enhancing data protection and user trust in IoT-enabled services. The results demonstrate significant differences in key generation and encryption times between cryptographic algorithms. RSA-4096 has the longest key generation time, taking 3.0 seconds, indicating its computational complexity. The Proposed algorithm, on the other hand, performs faster with a key generation time of 0.3 seconds. The Proposed algorithm offers a good balance of speed and security, compared to RSA-4096, which offers strong security but comes at a cost. The cloud computing performance metrics demonstrate significant values in Network Bandwidth (Mbps), with a range reaching up to 700 Mbps, followed by Throughput (req/sec) at around 500 req/sec, indicating the system’s capability to handle high traffic. The Latency (ms), Response Time (ms), and Disk I/O Speed (MB/s) show balanced performance, ensuring quick data transmission and efficient storage, confirming the robustness of the proposed methodology for secure and efficient cloud-based data management.
