A lightweight hardware implementation of CRYSTALS-Kyber

Journal of Information and Intelligence
The security of cryptographic algorithms based on integer factorization and discrete logarithm will be threatened by quantum computers in future. Since December 2016, the National Institute of Standards and Technology (NIST) has begun to solicit post ...

Post-Quantum Wireless-Based Key Encapsulation Mechanism via CRYSTALS-Kyber for Resource-Constrained Devices

IEEE Access
We consider the problem of adapting a Post-Quantum cryptosystem to be used in resource-constrained devices, such as those typically used in Device-to-Device and Internet of Things systems.

Applying the Simple Partial Discard Method to Crystals-Kyber

IEEE Access
In certain cryptographic applications random numbers are required (e.g., when generating cryptographic keys and generating digital signatures). To obtain these random numbers, the typical approach involves obtaining random bits first and then converting ...

Towards CRYSTALS-Kyber VHDL Implementation [PDF]

Proceedings of the 18th International Conference on Security and Cryptography, 2021
Kyber is one of the three finalists of the National Institute of Standards and Technology (NIST) post-quantum cryptography competition. This article presents an optimized Very High Speed Integrated Circuit Hardware Description Language (VHDL)-based implementation of the main components of the Kyber scheme, namely Number-Theoretic Transform (NTT) and ...

Lattice codes for CRYSTALS-Kyber

Designs, Codes and Cryptography, 2023
<p>This letter describes a lattice encoder for the NIST-recommended post-quantum encryption algorithm: Kyber. The key idea is to refine the analysis of Kyber decoding noise. We prove that Kyber decoding noise can be bounded by a sphere. This result shows the Kyber encoding problem is essentially a sphere packing in a hypercube.

Efficient Continuous Key Agreement With Reduced Bandwidth From a Decomposable KEM

IEEE Access, 2023
Continuous Key Agreement (CKA) is a two-party protocol used in double-ratchet protocols such as signal. It enables continuous and synchronous key distribution that generates a fresh key to encrypt each transaction in messenger apps. It guarantees forward

Correlation Electromagnetic Analysis on an FPGA Implementation of CRYSTALS-Kyber

2023 18th Conference on Ph.D Research in Microelectronics and Electronics (PRIME), 2023
Post-quantum cryptography represents a category of cryptosystems resistant to quantum algorithms. Such schemes are under the scrutiny of their mathematical security in the context of the NIST standardization process, but they are not side-channel secure at the algorithm level.

Secure post‐quantum group key exchange: Implementing a solution based on Kyber

IET Communications, Volume 17, Issue 6, Page 758-773, April 2023., 2023
In this article, the authors report on the implementation of a post‐quantum group key exchange protocol, which is proven secure in the so‐called Quantum Random Oracle Model. It is based on a two‐party design called Kyber, which is a finalist in the NIST standardization contest for post‐quantum cryptographic designs.

Lattice‐based cryptosystems in standardisation processes: A survey

IET Information Security, Volume 17, Issue 2, Page 227-243, March 2023., 2023
Abstract The current widely used public‐key cryptosystems are vulnerable to quantum attacks. To prepare for cybersecurity in the quantum era, some projects have been launched to call for post‐quantum alternatives. Due to solid security and desirable performance, lattice‐based cryptosystems are viewed as promising candidates in the upcoming ...
