The ever-increasing problem for our present-day healthcare system is to keep patient data secured and medical devices’ integrity intact amidst ever-so-widening interconnections. This paper presents an exceptional security architecture for Medical Body Area Networks (MBANs), incorporating hybrid algorithms of homomorphic encryption and Blowfish encryption in data protection and privacy. Our framework combines sophisticated cryptographic techniques with real-time monitoring capabilities against cybersecurity threats like unauthorized access and data breach in MBAN environments. The design of this framework is discussed in detail with respect to encryption techniques, data transmission protocols, and device interoperability provisions. Evaluation and validation of our framework reveal a better performance on robustness as well as efficacy toward possible security risks and contribute to the safety and robustness of MBAN deployments. The continuous refinement and adaptation mechanisms ensure that this framework is responsive against emerging threats and developed regulatory norms; hence making it a great asset for healthcare organizations to comply with patient confidentiality and compliance standards even in an increasingly evolving digital healthcare landscape.
