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 ...
