A Base‐Mediated Rearrangement of the Benzylic 1,5‐Hexadipyridynyl Moiety

ChemPlusChem, Volume 90, Issue 9, September 2025.
A rearrangement unheard of! When exposed to base, benzylic 1,5‐hexadipyridynyl moieties skip a beat—disregarding Cope‐like rearrangement and instead readily rearrange through a deprotonation–reprotonation–electrocyclization cascade. The result is a highly rigid vinyl‐pyridine cyclobutene, fashioned via a novel pathway.A previously unrecognized base ...

Accelerating NTT with RISC-V Vector Extension for Fully Homomorphic Encryption

Transactions on Cryptographic Hardware and Embedded Systems
Fully Homomorphic Encryption (FHE) has gained increasing importance mainly due to its potential use in privacy-preserving cloud computing. This privacy stems from the computation being directly performed on data that is encrypted by the client. However,

NTTRU: Truly Fast NTRU Using NTT

Transactions on Cryptographic Hardware and Embedded Systems, 2019
We present NTTRU – an IND-CCA2 secure NTRU-based key encapsulation scheme that uses the number theoretic transform (NTT) over the cyclotomic ring Z7681[X]/(X768−X384+1) and produces public keys and ciphertexts of approximately 1.25 KB at the 128-bit ...
