A Survey of Attacks on Large Language Models
Wenrui Xu, Keshab K. Parhi
Large language models (LLMs) and LLM-based agents have been widely deployed in a wide range of applications in the real world, including healthcare diagnostics, financial analysis,…
KyberMat: Efficient Accelerator for Matrix-Vector Polynomial Multiplication in CRYSTALS-Kyber Scheme via NTT and Polyphase Decomposition
Weihang Tan, Yingjie Lao, Keshab K. Parhi
CRYSTAL-Kyber (Kyber) is one of the post-quantum cryptography (PQC) key-encapsulation mechanism (KEM) schemes selected during the standardization process. This paper addresses opti…
Long Polynomial Modular Multiplication using Low-Complexity Number Theoretic Transform
Sin-Wei Chiu, Keshab K. Parhi
This tutorial aims to establish connections between polynomial modular multiplication over a ring to circular convolution and discrete Fourier transform (DFT). The main goal is to…
