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 ...

Hardness of (Semiuniform) MLWE with Short Distributions Using the Rényi Divergence
IET Information Security, Volume 2023, Issue 1, 2023., 2023 The module learning with errors (MLWE) problem has attracted considerable attention for its tradeoff between security and efficiency. The quantum/classical worst‐case to average‐case hardness for the MLWE problem (or more exactly, a family of problems) has been established, but most of the known results require the seed distribution to be the uniform ...

Hardness of Module‐LWE with Semiuniform Seeds from Module‐NTRU
IET Information Security, Volume 2023, Issue 1, 2023., 2023 The module learning with errors (MLWE) problem has attracted significant attention and has been widely used in building a multitude of lattice‐based cryptographic primitives. The hardness of the MLWE problem has been established for several variants, but most of the known results require the seed distribution (i.e., the distribution of matrix A) to be ...

A side-channel attack on a masked hardware implementation of CRYSTALS-Kyber
Journal of Cryptographic Engineering, 2023 Abstract NIST has recently selected CRYSTALS-Kyber as a new public key encryption and key establishment algorithm to be standardized. This makes it important to evaluate the resistance of CRYSTALS-Kyber implementations to side-channel attacks. Software implementations of CRYSTALS-Kyber have already been thoroughly analysed.
