Survey of Emerging Technology Based Physical Unclonable Funtions

摘要: Authentication of electronic devices has become critical. Hardware authentication is one way to enhance security a chip. Along with software, it makes harder for an intruder access any computer, smart-phone, or other without authorization. One authenticating device through hardware use the fabrication anomalies, which are random and unclonable. This mechanism called Physical Unclonable Function (PUF). PUFs easy evaluate but hard predict. PUF concept that gained popularity since past decade, when researchers started taking advantage randomness electrical signals in order build unique block. survey will show state-of-the-art currently investigated as PUFs. The different technologies compared by into account reproducibility, uniqueness, randomness, area, scalability, compatibility CMOS. Emphasis put on emerging gaining commercial interest. Through comparisons, we their applicability environments.
