Low-Complexity SVD-Based Precoding over Zero-Padded ISI Channels
Shuiyin Liu, Amin Sakzad
We propose a low-complexity SVD-based transceiver for zero-padded memory- ISI channels. Appending a single zero-padding symbol to an -symbol block yields an ch…
On the Maximum Toroidal Distance Code for Lattice-Based Public-Key Cryptography
Shuiyin Liu, Amin Sakzad
We propose a maximum toroidal distance (MTD) code for lattice-based public-key encryption (PKE). By formulating the encryption encoding problem as the selection of points…
Compact Lattice-Coded (Multi-Recipient) Kyber without CLT Independence Assumption
Shuiyin Liu, Amin Sakzad
This work presents a joint design of encoding and encryption procedures for public key encryptions (PKEs) and key encapsulation mechanism (KEMs) such as Kyber, without relying on t…
Joint Power and Bit Allocation for Precoded Massive MIMO Channels
Shuiyin Liu, Amin Sakzad
This work addresses the joint optimization of power and bit allocation in precoded large-scale n x n MIMO systems with discrete input alphabets, specifically QAM constellations. We…
Lattice-Based Vulnerabilities in Lee Metric Post-Quantum Cryptosystems
Anna-Lena Horlemann, Karan Khathuria, Marc Newman +2
Post-quantum cryptography has gained attention due to the need for secure cryptographic systems in the face of quantum computing. Code-based and lattice-based cryptography are two…
Semi-Compressed CRYSTALS-Kyber
Shuiyin Liu, Amin Sakzad
In this paper, we investigate the communication overhead of the Kyber, which has recently been standardized by the National Institute of Standards and Technology (NIST). Given the…
CRYSTALS-Kyber With Lattice Quantizer
Shuiyin Liu, Amin Sakzad
Module Learning with Errors (M-LWE) based key reconciliation mechanisms (KRM) can be viewed as quantizing an M-LWE sample according to a lattice codebook. This paper describes a ge…
