Authentication is an essential cryptographic primitive that confirms the identity of parties
during communications. For security, it is important that these identities are complex, in order …

Counterfeit medicines are a fundamental security problem. Counterfeiting medication poses
a tremendous threat to patient safety, public health, and the economy in developed and less …

The possibility to tailor photoluminescence (PL) of monolayer transition metal
dichalcogenides (TMDCs) using external factors such as strain, doping, and external …

P–n junctions based on 2D materials can be achieved using a selective doping technique,
while such a method is challenged by the complex fabrication process. Here, a facile van …

The conventional nanoscale anti-counterfeiting scheme, exhibiting limited encoding
capacity, faces growing challenges of being falsified with the advent of advanced high …

Interest in two-dimensional (2D) transition metal dichalcogenide materials has recently
grown due to their tunable band gap, large exciton binding energy, and flexibility in …

Physically unclonable crypto primitives have potential applications for anti-counterfeiting,
identification, and authentication, which are clone proof and resistant to variously physical …

We have shown the opportunity to use the unique inhomogeneities of the internal structure
of an optical fiber waveguide for remote authentication of users or an optic fiber line. Optical …

In the era of hyperconnected contemporary society, hardware and information security
become more dependent on advanced cryptographic primitives. A physically unclonable …
