Himanshu Jain, Neelesh Kumar Gupta · 2024
Bluetooth low energy (BLE) technology has gained widespread adoption in various applications but concerns about user privacy and tracking have emerged. In this research article, we propose a privacy-enhancing algorithm specifically designed for BLE to address these concerns. Our algorithm ensures user anonymity and protects sensitive information during BLE communication. We evaluate the effectiveness of our method through experiments and comparisons with existing techniques, demonstrating its ability to mitigate privacy risks and safeguard user data. The increasing prevalence of wearable devices in various domains has raised concerns about data security and privacy. BLE technology is commonly used for communication in wearable devices due to its low power consumption. However, the inherent vulnerabilities of BLE in terms of data security necessitate the integration of robust encryption algorithms. In this study, we propose the integration of BLE with advanced encryption standard-counter with CBC-MAC (AES-CCM) as an effective solution to enhance data security in wearable devices. The proposed algorithm leverages the low energy consumption capabilities of BLE while providing a strong encryption mechanism through AES-CCM. By combining these technologies, data confidentiality, integrity, and privacy are effectively ensured during communication between wearable devices. AES-CCM offers encryption and authentication in a single operation, reducing computational overhead and enhancing the efficiency of secure data transmission. To evaluate the proposed algorithm, we conducted performance evaluations and efficiency analyses. The results demonstrated that the integration of BLE with AES-CCM strikes a balance between data security and low power consumption, making it a suitable choice for wearable devices. The algorithm showcased improved privacy protection, reduced vulnerability to attacks, and efficient energy utilization.
