  author={Brian C. Grubel and Bryan T. L. Bosworth and Michael R. Kossey and A. Brinton Cooper and Mark A. Foster and Amy C. Foster},
We present a comprehensive investigation into the complexity of a new private key storage apparatus: a novel silicon photonic physical unclonable function (PUF) based on ultrafast nonlinear optical interactions in a chaotic silicon microcavity that is both unclonable and impossible to emulate. This device provides remarkable improvements to total information content (raw cryptographic material), information density, and key generation rates over existing optical scattering PUFs and is also more…

Physically secure and fully reconfigurable data storage using optical scattering

A PDLC-based device that functions as an integrated optical physical unclonable function (PUF) that can selectively access a dense set of non-electronically saved random bits and fully erase and transform these bits into a new random configuration in less than one second, via a simple electrical signal.

Silicon is evolving as a versatile photonic platform with multiple functionalities that can be seamlessly integrated. The tool box is rich starting from the ability to guide and amplify multiple

Physical key-protected one-time pad

The ability to securely couple the randomness contained within two unique physical objects can extend to strengthen hardware required by a variety of cryptographic protocols, which is currently a critically weak link in the security pipeline of the authors' increasingly mobile communication culture.

Optical PUFs Reloaded

The first prototype of an integrated optical PUF that functions without moving components is built and its security is investigated, showing that these PUFs can surprisingly be attacked by machine learning techniques if the employed scattering structure is linear, and if the raw interference images of the PUF are available to the adversary.

Cloning Physically Unclonable Functions

This work demonstrates that SRAM PUFs are not well suited as PUFs, as they do not meet several requirements that constitute an ideal PUF and produces the first physical clone of a Physically Unclonable Function was produced.

Nonlinear Group IV photonics based on silicon and germanium: from near-infrared to mid-infrared

Optical storage arrays: a perspective for future big data storage

A review of the recent advancements in nanophotonics-enabled optical storage techniques is presented and developments in ’super-resolution recording‚, which allow a light-sensitive material to be exposed to a focal spot that is smaller than the diffraction limit of light, will allow the size of recorded bits to shrink to just a few nanometres in size.

Physical Unclonable Functions and Applications: A Tutorial

This paper motivates the use of PUFs versus conventional secure nonvolatile memories, defines the two primary PUF types, and describes strong and weak PUF implementations and their use for low-cost authentication and key generation applications.
