Physical Unclonable Function Techniques Applied for Digital Hardware Protection
, 2013 Privacy is an important property that is growing harder to keep as people develop new ways to steal information from users on their computers. Software alone cannot ensure privacy since an infected system is untrustworthy.

A modelling attack resistant low overhead memristive physical unclonable function [PDF]
, 2020 Memristors are finding applications in memory, logic, neuromorphic systems, and data security. To this end, we leverage the non-linear behaviour of memristors to devise a low overhead physical unclonable function using a memristive chaos circuit in ...

Flowchart description of security primitives for Controlled Physical Unclonable Functions [PDF]
, 2009 Physical Unclonable Functions (PUFs) are physical objects that are unique, practically unclonable and that behave like a random function when subjected to a challenge. Their use has been proposed for authentication tokens and anti-counterfeiting.

Circuit Implementation of Multibit-generating Memristive Physical Unclonable Function
, 2021 최근 IoT 기술의 상용화가 빨라지면서 언제 어디서든 인터넷을 통해 다양한 기기들을 제어할 수 있는 시대가 되었다. 하지만 IoT 환경에서는 디바이스들이 인터넷에 연결되어 정보를 수집, 전송, 활용하는 과정을 거치기 때문에, 이러한 특성상 쉽게 보안 위협을 받는다. 소프트웨어 기반 보안 시스템은 저렴한 가격과 간단한 업데이트 방식과 같은 장점을 통해 이러한 한계를 극복하고자 했지만, 그 구조적 위험성으로 인해 최근에는 하드웨어 보안 시스템이 많은 ...
