This paper questions the side-channel security of central reduction technique. which is widely adapted in efficient implementations of Lattice-Based Cryptography (LBC). We show that the central reduction leads to a vulnerability by creating a strong dependency between the power consumption and the sign of sensitive intermediate values. We exploit this dependency by introducing the nov... https://www.hindigyanvishv.com/flash-deal-Iowa-Cubs-Foam-Finger-p32059-hot-value/
