As artificial intelligence accelerates the rise of highly convincing deepfakes and quantum computing inches closer to practical deployment, researchers at Florida International University (FIU) have introduced a quantum-safe encryption system designed to defend digital content against next-generation cyberattacks. The breakthrough directly addresses growing concerns that powerful quantum computers could one day break today’s encryption standards, potentially exposing financial networks, government communications, healthcare records, and digital media to widespread compromise.
Currently, most encryption systems rely on mathematical complexity that would take classical computers years or even decades to break. However, quantum computing introduces a fundamentally different approach to processing information. As a result, cybersecurity experts warn that once quantum systems mature, they could rapidly dismantle widely used cryptographic protections.

“Think of a regular computer hack as someone trying to pick a traditional door lock – it could take days, even years, to try every combination. But a quantum computer hack is like having a key that could try multiple combinations simultaneously. This is what makes quantum threats so powerful,” said S.S. Iyengar, Knight Foundation School of Computing and Information Sciences Professor and director of the Digital Forensic Center of Excellence at FIU, who led the research.
To counter this risk, the FIU research team developed a hybrid solution that integrates quantum encryption principles with secure internet transmission protocols. Their work, funded by the U.S. Army Research Office and published in IEEE Transactions on Consumer Electronics, outlines a system that secures videos within a digital “lockbox.” This lockbox scrambles data using cryptographic keys that only authorized users can decode, thereby preventing both traditional and future quantum-enabled attacks.
Importantly, the team tested the system against advanced encryption techniques currently in use. During trials, the FIU method outperformed comparable solutions by 10–15%. Moreover, researchers observed a significant reduction in exploitable data patterns structural weaknesses that hackers typically exploit to reverse-engineer encrypted files. Consequently, encrypted videos became substantially more resistant to cracking attempts.

Although quantum-driven attacks remain largely theoretical today, cybersecurity agencies worldwide are urging organizations to begin transitioning toward post-quantum cryptography. For example, in 2025, the National Cyber Security Centre in the United Kingdom advised major institutions to modernize their cryptographic systems by 2035 to prepare for quantum-enabled threats. Therefore, proactive innovation in quantum-safe encryption is no longer optional but increasingly essential.
Beyond preventing data breaches, the researchers emphasize that stronger encryption could also mitigate emerging risks tied to AI-generated deepfakes. As digital manipulation becomes more sophisticated, securing video authenticity and transmission integrity will play a critical role in preventing fraud, identity theft, and misinformation.
To accelerate real-world deployment, FIU researchers are collaborating with QNu Labs, a cybersecurity firm specializing in quantum technologies. Together, they are advancing the platform toward commercial readiness. Additionally, the team is scaling the solution to handle full-length video files and real-time streaming applications, including video conferencing platforms and surveillance systems.
Iyengar conducted the research alongside Yashas Hariprasad of California State University, East Bay, and Naveen Kumar Chaudhary of India’s National Forensic Sciences University. As quantum computing capabilities continue to evolve, this collaborative innovation positions FIU at the forefront of securing digital infrastructure against the next era of cyber threats.
