Fortifying cloud-based healthcare: a link load balancer infused with NTRU, honey, and proxy algorithms for robust identity and access management

Cloud-based IoMT has transformed healthcare and improved patient care but also exposed new security vulnerabilities. Medical data's sensitivity and its critical role in healthcare make the sector a prime target for cyberattacks, with data breaches and ransomware incidents on the rise. The growing threat of quantum computing to current cryptographic methods further compounds the issue. Our study addresses these challenges by proposing a comprehensive security framework for healthcare systems. It introduces three key innovations: quantum resistant NTRU cryptography for long-term data protection, deceptive honey algorithms for proactive threat monitoring, and robust proxy algorithms to prevent unauthorised access and data breaches. The framework also optimises load balancing for better resource utilisation and faster response times. This multi-dimensional approach tackles both current and future cyber threats, offering a scalable solution that ensures confidentiality, integrity, and availability of medical data. Its principles can also be applied to other critical infrastructure sectors facing similar cybersecurity challenges.
