Abstract
The incorporation of wireless body sensor networks (WBSNs) in medical applications has increased widely in recent years. WBSN provide an effective way to monitor patients’ health data remotely, and they also help to maintain social distancing. Hence, data safety is the utmost concern for maintaining the integrity of sensitive data as these risks can lead towards the life-threatening conditions of the patients, as well. To maintain the required level of security, many traditional cryptographic measures are currently in use; however, they cannot provide the same level of security in the quantum era. Therefore, in this paper, an augmented BB84 quantum cryptography protocol is proposed for secure key generation and distribution between two participating entities in a quantum environment. In addition, to preserve the legitimacy of the users, a hash-based message authentication code (HMAC) is incorporated into the proposed model. Through different analysis including security, key generation time, multiple error rate analysis, and performance analysis, it is evident that the proposed model provides prominent security against DoS attack, replay attack, quantum attack, and known plaintext attack. Moreover, the key generation time (ms) is reduced by 89.38% compared to the existing quantum key agreement scheme. In addition, it achieves an average execution time (ms) for evaluating the protocol at different error rates like 1%, 5%, and 10%, are 0.0198%, 0.0736%, and 0.0385%, respectively, for different key lengths (KB). This demonstrates the robustness, reliability, and security tolerance of the proposed scheme under varying channel noise and attack conditions.
