en.Wedoany.com Reported - A research team at the Massachusetts Institute of Technology (MIT) has successfully developed an ultra-efficient microchip designed to protect wireless biomedical devices such as insulin pumps and pacemakers from future quantum computer attacks. This custom chip is only about the size of an extremely fine needle tip, yet its energy efficiency is 20 to 60 times better than other post-quantum security technologies, addressing the critical energy consumption constraints that have long challenged battery-powered medical implants.
The core goal of this research is to provide a viable post-quantum security solution for energy-constrained edge devices. Seoyoon Jang, a graduate student in MIT's Department of Electrical Engineering and Computer Science and the lead author of the research paper, stated: "Tiny edge devices are everywhere, and biomedical devices are often the most vulnerable targets because power constraints prevent them from having state-of-the-art security. We have demonstrated a very practical hardware solution to protect patient privacy." The research was led by senior author Anantha Chandrakasan, MIT's provost and a professor in the Department of Electrical Engineering and Computer Science, and the related findings have been published at the IEEE Custom Integrated Circuits Conference.
Based on an Application-Specific Integrated Circuit (ASIC) design, the microchip drastically reduces the energy required to run Post-Quantum Cryptography (PQC) algorithms. While PQC algorithms can resist attacks from quantum computers, their computational complexity is extremely high, previously increasing device power consumption by two to three orders of magnitude, which is impractical for resource-constrained wearable, ingestible, or implantable devices. To achieve top-tier security at very low power, the research team adopted a multi-pronged design strategy. The chip integrates two different PQC schemes internally, which not only enhances security but also reserves space for potential future technological evolution. Simultaneously, the chip incorporates an efficient on-chip true random number generator for key generation, outperforming external chip solutions.
Beyond algorithmic security, the chip also features hardware defenses specifically against physical attacks. It includes countermeasures against power side-channel attacks, preventing hackers from stealing user data such as a patient's social security number or device credentials by analyzing variations in the device's power consumption. To strike a balance between security and energy consumption, the chip implements redundant design only in critical parts, avoiding a significant overall increase in energy use. Furthermore, it possesses an early fault detection function that can promptly abort operations during voltage fluctuations, thereby saving energy.
The real-world urgency of this technological breakthrough stems from two aspects. On one hand, institutions like the U.S. National Institute of Standards and Technology are gradually phasing out traditional encryption protocols in favor of stronger PQC algorithms. On the other hand, the industry widely believes that the rapid advancement of quantum hardware makes the implementation of post-quantum encryption more pressing. The creation of this chip opens new pathways for scenarios requiring powerful cryptographic algorithms to run at extremely low power. As wireless sensors and the Internet of Things expand in the healthcare sector, the potential attack surface continues to grow, making such low-power, high-security solutions significant for protecting the expanding network of connected health technologies.
In the future, the application scenarios for this chip are expected to extend far beyond the medical field. The research team plans to expand this technology to other vulnerable edge devices, such as industrial sensors and smart inventory tags. This research leverages the expertise of the MIT Schwarzman College of Computing and the Department of Electrical Engineering and Computer Science, and received partial funding from the U.S. Advanced Research Projects Agency for Health.
