SUTD researchers, in collaboration with the University of Cambridge, have developed a new phase-change physical unclonable function (PUF) device for enhanced hardware security, resistant to AI attacks. This device uses phase-change materials to generate unique cryptographic keys through the inherent randomness of their amorphous and crystalline states, offering a more secure alternative to traditional silicon-based PUFs. Applications include data security across various sectors, including consumer electronics and flexible, printable devices. The PUF’s reconfigurable mode provides additional security by generating a new key if needed.
