An Asymmetric Optical Cryptosystem Using Physically Unclonable Functions in the Fresnel Domain

Engineering Proceedings, 2023
In this paper, we propose a new asymmetric cryptosystem for phase image encryption, using the physically unclonable functions (PUFs) as security keys. For encryption, the original amplitude image is first converted into a phase image and modulated with a

Physical Unclonable Functions: A Primer

IEEE Security & Privacy, 2014
Physical unclonable functions (PUFs) make use of the measurable intrinsic randomness of physical systems to establish signatures for those systems. PUFs provide a means to generate unique keys that don't need to be stored in nonvolatile memory, and they offer exciting opportunities for new authentication and supply chain security technologies.

Creating and balancing the paths of arbiter-based physically unclonable functions on FPGA

Informatika, 2022
Objectives. The problem of constructing a new structure of paths of physically unclonable function of the arbiter type (APUF) on the FPGA is being solved, based on the full use of internal resources of LUT-blocks, which are functionally repeaters.

CalyPSO: An Enhanced Search Optimization based Framework to Model Delay-based PUFs

Transactions on Cryptographic Hardware and Embedded Systems, 2023
Delay-based Physically Unclonable Functions (PUFs) are a popular choice for “keyless” cryptography in low-power devices. However, they have been subjected to modeling attacks using Machine Learning (ML) approaches, leading to improved PUF designs that ...

Improvement and Cryptanalysis of a Physically Unclonable Functions Based Authentication Scheme for Smart Grids

Mathematics, 2022
Authentication protocols are often used in smart grids to deliver the necessary level of security. A huge number of clients in such a system, however, provides the attacker with the ability to clone them, for example.
