This review begins by reviewing protocols of quantum key distribution based on discrete variable systems, and considers aspects of device independence, satellite challenges, and high rate protocols based on continuous variable systems.

This paper reviews this physical notion of security, focusing on quantum key distribution and secure communication, which relies entirely on the laws of quantum mechanics.

An organizational perspective of the post-quantum cryptography transition is presented and standards and recommendations for transitioning organizations to quantum-secure cryptographic protocols are outlined, including a discussion of transition timelines and the leading strategies to protect systems against quantum attacks.

Here, the feasibility, efficiency, and stability of the PQC algorithm in QKD authentication is experimentally verified, and the advantages when new users join theQKD network are demonstrated.

This work demonstrates the viability of quantum dots as light sources for entanglement-based quantum key distribution and quantum networks, and increases the excitation rate and embedding the dots in state-of-the-art photonic structures, key generation rates in the gigabits per second range are in principle at reach.

When elementary quantum systems, such as polarized photons, are used to transmit digital information, the uncertainty principle gives rise to novel cryptographic phenomena unachievable with traditional transmission media, e.g. a communications channel on which it is impossible in principle to eavesdrop without a high probability of disturbing the transmission in such a way as to be detected. Such a quantum channel can be used in conjunction with ordinary insecure classical channels to distribute random key information between two users with the assurance that it remains unknown to anyone else,...

Current state of the art on post-quantum cryptosystems and how they can be applied to blockchains and DLTs are studied, as well as their main challenges.

Entanglement-based quantum key distribution is demonstrated between two ground stations separated by 1,120 kilometres at a finite secret-key rate of 0.12 bits per second, without the need for trusted relays, which increases the secure distance on the ground tenfold and increases the practical security of QKD to an unprecedented level.

This paper demonstrates an architecture for accelerating the polynomial multiplication using number theoretic transform (NTT) using a small Artix-7 FPGA and proposes several optimization strategies for efficiency improvement targeting different performance requirements for various applications.

The National Institute of Standards and Technology is in the process of selecting public-key cryptographic algorithms through a public, competition-like process. The new public-key cryptography standards will specify additional digital signature, public-key encryption, and key-establishment algorithms to augment Federal Information Processing Standard (FIPS) 186-4, Digital Signature Standard (DSS), as well as NIST Special Publication (SP) 800-56A Revision 3, Recommendation for Pair-Wise Key-Establishment Schemes Using Discrete Logarithm Cryptography, and SP 800-56B Revision 2, Recommendation f...

RISQ-V is presented, an enhanced RISC-V architecture that integrates a set of powerful tightly coupled accelerators to speed up lattice-based PQC and extended the Risc-V ISA with 29 new instructions to efficiently perform operations for lattices-based cryptography.

The Information Technology Laboratory (ITL) at the National Institute of Standards and Technology (NIST) promotes the U.S. economy and public welfare by providing technical leadership for the Nation's measurement and standards infrastructure.ITL develops tests, test methods, reference data, proof of concept implementations, and technical analyses to advance the development and productive use of information technology.ITL's responsibilities include the development of management, administrative, technical, and physical

Experimental results show that VPQC can speed up several typical key encapsulation mechanisms (NewHope, Kyber and LAC) by an order of magnitude compared with previous state-of-the-art hardware implementations.

Starting with the historical evolution of computer and communications networks and their security, the book then arrives at the main definitions of cryptography and network security. Next, the basics of information theory, how to measure information, the information associated with a certain source are also discussed. Source codes are presented, along with the concepts of information transmission, joint information, conditional entropy, mutual information and channel capacity. Computer networks are discussed, including the main protocols and network architectures, and the important TCP/IP prot...

This book discusses Private-Key (Symmetric) Cryptography, Number Theory and Cryptographic Hardness Assumptions, and the Random-Oracle Model in Detail.

A cross-cutting systematization of the computer-aided cryptography literature, focusing on three main areas: (i) design-level security (both symbolic security and computational security), (ii) functional correctness and efficiency, and (iii) implementation- level security (with a focus on digital side-channel resistance).

With the advent of advanced technology, the IoT has made possible the connection of numerous devices that can collect vast volumes of data. Hence, the demands of IoT security is paramount. Cryptography is being used to secure the authentication, confidentiality, data integrity and access control of networks. However, due to the many constraints of IoT devices, traditional cryptographic protocols are no longer suited to all IoT environments, such as the smart city. As a result, researchers have been proposing various lightweight cryptographic algorithms and protocols to secure data on IoT netwo...

Two novel visual cryptography schemes are proposed by combining VC with single-pixel imaging (SPI) for the first time, where the secret image is shared by multiple illumination pattern sequences and it can be recovered when the visual key patterns are projected onto identical items.
