The healthcare sector is often targeted by cyber attacks. Healthcare data has personal and financial details that hackers want. They can use this data for identity theft, insurance fraud, or ransomware attacks. In 2024, the average cost of a data breach was $4.88 million. This is 10% more than in 2023, according to the Verizon Data Breach Investigations Report. The cost rise shows that cyber threats are becoming more common and more advanced.
Common Cyber Threats: Healthcare IT systems face many types of cyber threats. These include malware, phishing attacks, ransomware, and social engineering. These attacks try to disrupt work, steal information, or lock data to demand ransom payments. As healthcare providers use more digital tools, their risk of these attacks grows. This makes cybersecurity very important.
Rise of Quantum Computing: A new challenge is quantum computing. Quantum computers may break current encryption methods like RSA and ECC in 5 to 10 years, experts say. Quantum computing uses special algorithms, like Shor’s algorithm, to solve hard math problems quickly. This lets attackers break encrypted data faster. Hackers could save encrypted healthcare data now and decrypt it later when quantum computers are ready. This is called “harvest now, decrypt later.” It threatens patient privacy and research data.
Integration and Budget Constraints: One big problem in improving cybersecurity is adding new security methods to old healthcare IT systems. Many healthcare providers use systems that are hard to update. Also, budgets are limited and staff need special training. Healthcare leaders and IT managers often find it hard to balance daily work needs and cybersecurity costs.
To face the threat of quantum computing, the U.S. Department of Commerce’s National Institute of Standards and Technology (NIST) set new post-quantum cryptography (PQC) standards in August 2024. These standards offer new encryption methods strong enough to resist quantum attacks. Using these new methods quickly is important to protect healthcare data across the country.
Key PQC Algorithms:
These algorithms are based on math problems that should be safe from both classical and quantum attacks. They also use small and efficient keys. This makes them practical for healthcare systems that need speed and security.
Immediate Integration Urged: Dustin Moody, who leads the NIST PQC project, tells healthcare IT teams to start using these new standards right away. The switch will take time, but waiting too long could increase risks. It can take years to fully adopt new encryption systems. Starting early helps U.S. medical practices get ready before quantum computers become powerful enough to break current encryption.
Besides PQC, quantum security also uses Quantum Key Distribution (QKD). QKD sends cryptographic keys in quantum states. If someone tries to eavesdrop, the quantum state changes and this is detected right away. This method helps catch interception during communication quickly.
However, using QKD in healthcare has challenges. Facilities must upgrade infrastructure. There are limits on transmission distances and system compatibility. Because of this, hybrid cryptographic modes are being studied. These combine PQC with classical encryption for better performance and security.
Healthcare organizations protecting patient records, genomic data, and research can use PQC, QKD, and hybrid methods together. This can create a strong defense suited for future threats.
Artificial Intelligence (AI) is important in managing healthcare operations and security. AI and machine learning (ML) help by automating threat detection and response. This speeds up the reaction time when a cyber threat is found, which is very important in healthcare because of patient safety.
AI in Cyber Threat Detection: AI looks at large amounts of network and system data to find unusual patterns. These may show ransomware or phishing attacks. AI systems can learn and improve their detection over time. Advanced AI cybersecurity platforms respond to attacks by isolating threats and alerting human teams for more action.
AI and Post-Quantum Security Integration: AI can help improve PQC algorithms by watching encryption performance. It adjusts settings to balance security and speed. AI also helps improve authentication by recognizing user behavior and spotting unusual actions that might mean a breach or insider threat.
AI in Healthcare Workflow Automation: AI also helps automate administrative and clinical tasks. It is especially helpful in front-office work. For example, some companies use AI for phone automation and answering patient calls. These systems handle calls about appointments, billing, and prior authorizations that usually need many staff.
One big administrative challenge is prior authorization. This means getting approval from insurance before some treatments can start. It often takes a long time and adds work for staff.
New AI tools called agentic AI are being used to automate prior authorization. Agentic AI works on its own with little human help. It collects and reviews documents, checks rules, makes decisions about approval, and talks with insurance companies. This cuts down manual work and helps patients get care faster.
Raheel Retiwalla, Chief Strategy Officer at Productive Edge, says agentic AI is changing workflows like prior authorization, care coordination, and claims processing. Gartner named this technology as a top trend for 2025. It says healthcare leaders need to adopt agentic AI fast to improve productivity and reduce admin work.
Using AI and post-quantum security also brings some problems healthcare leaders must solve:
Putting in place quantum-safe cybersecurity and AI can cost a lot. Many medical practices have tight IT budgets. They find it hard to choose these technologies over immediate patient care needs.
Healthcare leaders should:
Many organizations and partnerships work to standardize and spread post-quantum cryptography and quantum security tools. The U.S. government passed the Quantum Cybersecurity Preparedness Act. It requires federal agencies to upgrade to PQC. This sets an example for other sectors.
Some technology companies, like Fortinet, added NIST’s PQC algorithms to their cybersecurity products early. This helps healthcare providers get access to quantum-safe tools faster.
Working together across industries is important to set best practices, share information about threats, and update standards as quantum and AI technology grow.
The mix of new post-quantum cryptography standards, quantum security tools, and AI automation gives U.S. healthcare a way to improve data safety and work efficiency in the next ten years. Early action, smart spending, and ongoing learning can help healthcare providers protect sensitive patient information while making workflows better in a fast-changing tech world.
Agentic AI refers to advanced autonomous AI systems capable of independently performing complex tasks, solving problems, and learning without human oversight. In healthcare, these systems streamline workflows such as care coordination and prior authorization by making decisions and adapting autonomously to improve efficiency and patient outcomes.
Agentic AI accelerates prior authorization by automating and expediting the review and approval processes. These AI agents manage documentation, verify criteria compliance, and make real-time decisions, reducing administrative burdens and delays, ultimately enhancing productivity and speeding patient access to required treatments.
Agentic AI agents improve efficiency by automating intricate workflows like claims processing and care coordination, reducing manual tasks, minimizing human error, and enabling continuous learning. This results in faster decision-making, resource optimization, and streamlined operations, leading to better patient care delivery and reduced operational costs.
AI Governance Security establishes standards and frameworks to ensure AI systems in healthcare operate safely, ethically, and reliably. It addresses algorithmic bias mitigation, transparency, accountability, and protection against cyber threats, fostering trust and compliance with legal and ethical requirements in AI-driven healthcare applications.
Beyond administrative tasks, agentic AI facilitates remote patient monitoring by continuously analyzing health data to detect timely medical interventions. Its ability to adapt and self-learn allows for proactive responses to patient condition changes, which optimizes care delivery and enhances patient safety and clinical outcomes.
Healthcare AI integration increases data security challenges such as vulnerability to cyberattacks and privacy breaches. Ensuring robust encryption methods, mitigating adversarial attacks, and developing post-quantum cryptography are crucial to protect sensitive patient data and maintain system integrity in the evolving digital healthcare landscape.
Ambient invisible intelligence uses sensors and machine learning within healthcare environments to create responsive spaces, such as ICU patient monitoring and infection control. It enhances patient safety and operational efficiency by seamlessly adapting to patient movement, environmental conditions, and compliance monitoring without explicit commands.
Transparency allows stakeholders to understand AI decision-making processes, enabling oversight and trust, while accountability ensures AI systems adhere to ethical and legal standards. Together, these promote responsible AI use, mitigate biases, and prevent adverse outcomes in sensitive areas like patient care and prior authorizations.
Post-quantum cryptography is essential for securing healthcare data against future quantum computing attacks. Techniques like lattice-based and multivariate cryptography aim to safeguard patient information by creating encryption methods resistant to quantum decryption capabilities, ensuring long-term confidentiality and trust.
Healthcare organizations should proactively assess AI readiness, develop governance frameworks for security and ethics, and adopt best practices outlined in readiness guides. Scaling agentic AI involves balancing automation benefits with transparency, bias mitigation, and continuous monitoring to maximize efficiency and maintain trust in prior authorization processes.
