Abstract “Classical keys,” ie, secret keys stored permanently in digital form in nonvolatile
memory, appear indispensable in modern computer security—but also constitute an obvious …

For photonic devices, structural disorder and light scattering have long been considered
annoying and detrimental features that were best avoided or minimized. This review shows …

Disordered photonic structures are promising for the realization of physical unclonable
functions—physical objects that can overcome the limitations of conventional digital security …

In this work, the concept of optical identification (OI) based on physical unclonable functions
is introduced for the first time, to our knowledge, in optical communication systems and …

Abstract A Physical Unclonable Function (PUF) is a device with unique behaviour that is
hard to clone hence providing a secure fingerprint. A variety of PUF structures and PUF …

Abstract The term “Internet of Things” is becoming increasingly popular and promising,
ushering in a new era of smarter connectivity across billions of gadgets. In the foreseeable …

The light propagation through a multimode fiber is used to increase information security
during data transmission without the need for cryptographic approaches. The use of an …

For the purpose of information transmission security, image scrambling is to encrypt the
image by changing the image pixel values and pixel positions. Based on the asymmetric …

The quest for practical cryptographic primitives that are robust against quantum computers is
of vital importance for the field of cryptography. Among the abundance of different …
