The Wiretap Channel for Capacitive PUF-Based Security Enclosures


Abstract: "In order to protect devices from physical manipulations, protective security enclosures were developed. However, these battery-backed solutions come with a reduced lifetime, and have to be actively and continuously monitored. In order to overcome these drawbacks, batteryless capacitive enclosures based on Physical Unclonable Functions (PUFs) have been developed that generate a key-e... » read more

Power/Performance Bits: June 1


Stronger PUFs Researchers from Ohio State University and Potomac Research propose a new version of physical unclonable functions, or PUFs, that could be used to create secure ID cards, to track goods in supply chains, and as part of authentication applications. "There's a wealth of information in even the smallest differences found on computers chips that we can exploit to create PUFs," sai... » read more

A Novel Complementary Architecture of One-time-programmable Memory and Its Applications as Physical Unclonable Function (PUF) and One-time Password


Abstract "For the first time, we proposed a 2T complementary architecture of one-time-programmable memory (OTP) in a foundry logic CMOS chip. It was then used to realize the PUF (Physical unclonable function), and the combination with the AI technology to provide a one-time password capability. At first, an OTP was developed based on a novel 2T CMOS unit cell. The experimental results show t... » read more
