A Pipelined Hardware Design of FNTT and INTT of CRYSTALS-Kyber PQC Algorithm

Information
Lattice-based post-quantum cryptography (PQC) algorithms demand number theoretic transform (NTT)-based polynomial multiplications. NTT-based polynomials’ multiplication relies on the computation of forward number theoretic transform (FNTT) and inverse ...

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

Self‐Directed Teaching Strategies and Professional Learning in Technological Implementation: A Collaborative Autoethnography

International Journal of Applied Linguistics, EarlyView.
ABSTRACT Technological integration into teaching offers significant pedagogical potential, yet it can also intensify the challenge of addressing systemic barriers to inclusion. This issue is especially important for teaching‐focused academics (TAs), who are increasingly leading classroom instruction and translating institutional digital priorities into

Formally Verified Number-Theoretic Transform [PDF]

In recent years, the number-theoretic transform (NTT) has become increasingly common in cryptography, in part due to multiple lattice-based cryptographic schemes being selected for standardization during the NIST PQC competition.
