A note on the implementation of the Number Theoretic Transform [PDF]

, 2018
The Number Theoretic Transform (NTT) is the time critical function required by cryptographic protocols based on the Ring Learning With Errors problem (RLWE),a popular choice for post-quantum cryptography. Here we apply a simple methodology to convert the

Optimization of Parallel Number Theoretic Transform Algorithms for Multi-Core Digital Signal Processors [PDF]

Journal of Universal Computer Science
The Number Theoretic Transform (NTT), a finite-field variant of FFT, is critical in cryptography and digital signal processing, but its efficiency on FT-M7032 Digital Signal Processors(DSPs) remains suboptimal due to memory bottlenecks and ...

Number Theoretic Transforms for Secure Signal Processing [PDF]

IEEE Transactions on Information Forensics and Security, 2017
Multimedia contents are inherently sensitive signals that must be protected whenever they are outsourced to an untrusted environment. This problem becomes a challenge when the untrusted environment must perform some processing on the sensitive signals; a paradigmatic example is Cloud-based signal processing services.

NTT and Inverse NTT Quantum Circuits in CRYSTALS-Kyber for Post-Quantum Security Evaluation

Applied Sciences, 2023
The emergence of quantum computers threatens current cryptographic systems, and NIST is preparing for the post-quantum era through the post-quantum cryptography (PQC) contest. CRYSTALS-Kyber is a lattice-based cipher suite that is used as a PQC standard.

New number theoretic transform

Electronics Letters, 1992
A new number theoretic transform is introduced. This transform is defined modulo the Mersenne primes, has long transform length which is a power of two, a fast algorithm, and the inverse transform has within a factor of (1/N) the same form as the forward transform. Thus, it is well suited for the calculation of error free convolutions and correlations.

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

FEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

Barrett Modular Multiplication Optimization for Accelerating Number Theoretic Transform

Sci
The practicality of post-quantum lattice-based schemes is crucial for their real-world applications. Integrating these schemes requires efficient implementations through hardware, software, and algorithmic optimisation to achieve the necessary speed and ...

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

FEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Algebraic Linear Analysis for Number Theoretic Transform in Lattice-Based Cryptography

Transactions on Cryptographic Hardware and Embedded Systems
The topic of verifying postquantum cryptographic software has never been more pressing than today between the new NIST postquantum cryptosystem standards being finalized and various countries issuing directives to switch to postquantum or at least ...
