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

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 ...

Electrification and Child Work: Direct and Spillover Effects in Ethiopia

Sustainable Development, EarlyView.
ABSTRACT While electrification is often promoted for improving adults' labor supply, its effect on child work remains underexplored. Using four waves of Ethiopian panel data, we examine how electrification affects children's work time. By differentiating between households with and without own electricity access within electrified communities, we ...
