JEDDAH: Researchers at King Abdullah University of Science and Technology have developed technology that enhances the reliability of digital devices by relying on their unique physical characteristics, potentially offering a faster and more secure alternative to conventional passwords and security keys.
Published in Nature Electronics, the research addresses a growing challenge facing the digital systems that power cloud computing, artificial intelligence, and connected devices.
As these networks grow, so does the need to confirm that every device communicating within them is genuine and has not been copied or compromised.
The system uses tiny laser devices to generate unique digital fingerprints. Just as no two human fingerprints are exactly alike, each laser produces its own distinctive light pattern that can be used to verify identity. The researchers then combined the technology with AI, enabling the system to recognize and authenticate those fingerprints almost instantly.
Assistant Prof. Yating Wan, who led the research at KAUST, said: “Our approach explores whether devices can identify themselves using characteristics that are inherently part of the hardware.”
