摘要: Physical unclonable functions (PUFs) exploit the intrinsic complexity and irreproducibility of physical systems to generate secret information. The advantage is that PUFs have potential provide fundamentally higher security than traditional cryptographic methods by preventing cloning devices extraction keys. Most PUF designs focus on exploiting process variations in Complementary Metal Oxide Semiconductor (CMOS) technology. In recent years, progress nanoelectronic such as memristors has demonstrated prevalence scaling electronics down nano region. this paper, we extremely large information density available nanocrossbar architectures significant resistance develop an on-chip memristive device based strong (mrSPUF). Our novel architecture demonstrates desirable characteristics PUFs, including uniqueness, reliability, number challenge-response pairs (CRPs) PUFs. More significantly, contrast most existing our can act a reconfigurable (rPUF) without additional hardware benefit applications needing revocation or update secure key
