In our hyper-connected world, encrypted communications are crucial for everyday activities such as online shopping, digital signatures, bank transactions, and monitoring fitness trackers. However, today's encryption methods, which transform data into unreadable formats to secure information, are facing increasing threats from sophisticated cybercriminals and the looming advent of quantum computing. Cybersecurity firm JP Morgan repels 45 billion hacking attempts daily, highlighting the severity of current vulnerabilities. The most significant threat is Y2Q or Q-Day, the date when quantum computers will render most current encryption methods obsolete. Quantum computers, leveraging properties like superposition and entanglement, can explore multiple computational paths simultaneously, vastly accelerating their processing speed. For instance, a quantum computer could crack RSA-2048 encryption, which currently secures the internet, in a day rather than the millennia required by the world's fastest supercomputer. Without robust encryption, the security of our interconnected world would severely erode, posing risks to societal stability. A multidisciplinary research team led by Boston University (BU) is tackling these challenges with a physics-inspired approach to data security and privacy. Collaborating with experts from Cornell University and the University of Central Florida, the team aims to develop more resilient, scalable, and future-ready encryption methods. Principal investigator Andrei Ruckenstein, a distinguished professor of physics at BU, emphasizes the urgency and complexity of these challenges and highlights the potential paradigm shift their work represents. Modern encryption, developed about 50 years ago, primarily protects data in transit or at rest but leaves it exposed during use. This exposure is particularly problematic for data-intensive applications such as AI training models, which often handle confidential information. Current methods require models to decrypt data during training, increasing vulnerability, or employ privacy-preserving techniques that slow down processing, hindering scalability. The BU-led project introduces Encrypted Operator Computing (EOC), an innovative method that allows for direct computation on encrypted data. EOC combines principles from physics, computer science, and mathematics to create a scalable solution for secure data processing. Unlike Fully Homomorphic Encryption (FHE), another advanced cryptographic tool that has struggled to achieve practicality at scale, EOC aims to provide efficient, real-world applications. Claudio Chamon, a BU professor of physics, explains that the EOC method is inspired by quantum computation. By treating computational complexity as a thermodynamic quantity, the team relates the disorder and randomness of gate arrangements in a circuit to physical concepts like entropy. Entropy, in this context, measures the unpredictability or randomness of a system, similar to the way heat disperses in a cup of coffee, making it impossible to trace the precise movement of individual molecules. In their framework, computation is represented as a circuit of logical gates performing elementary operations. To enhance security and privacy, the team proposes a dynamic process to obfuscate, or hide, the circuit by rearranging these gates. This process scrambles information effectively, ensuring that even if a circuit is intercepted, it cannot be reverse-engineered due to the lack of discernible patterns. Program obfuscation is a powerful tool for protecting data and its processing, applicable in various scenarios such as blockchain transactions, medical AI models, and cloud services. Ran Canetti, a BU professor of computer science, notes that constructing a practical, general-purpose program obfuscation scheme has been elusive. The EOC project holds promise in making this a reality. The collaboration fosters a convergent research approach, integrating knowledge from multiple disciplines. This cross-disciplinary synergy accelerates the development of new algorithms and hardware, aiming to make secure, privacy-preserving computing widely accessible and practical. Timothy Riley, a mathematician from Cornell University, views the interdisciplinary collaboration as a rare opportunity to bridge language and perspective gaps, leading to innovative solutions. Industry insiders view the EOC project as a significant step forward in cryptography. They believe that by merging physics, computer science, and mathematics, the team can address the pressing need for secure data handling, especially in the quantum era. The Hariri Institute for Computing at BU, which supports the project, underscores the importance of breaking down silos in research to solve complex challenges. Yannis Paschalidis, a distinguished professor of engineering and director of the Hariri Institute, emphasizes that the work demonstrates how convergent research can drive real-world impact and open new technological frontiers. Boston University, known for its commitment to cutting-edge research and innovation, hosts the Quantum Convergence Focused Research Program, which facilitates multidisciplinary collaborations. This program has been instrumental in advancing the EOC project, bringing together experts from diverse fields to tackle critical cybersecurity issues. The team's ambitious goal is to create practical tools that can enhance data security and privacy, preparing for both present threats and the quantum future.
