Abstract: Various embodiments relate to a data processing system comprising instructions embodied in a non-transitory computer readable medium, the instructions for a cryptographic operation using masked compressing of coefficients of a polynomial having ns arithmetic shares for lattice-based cryptography in a processor, the instructions, including: shifting a first arithmetic share of the ns arithmetic shares by an input mask ?1; scaling the shifted first arithmetic share by a value based on a first compression factor ? and a masking scaling factor ?1; shifting the scaled first arithmetic share by a value based on the masking scaling factor ?1; scaling a second to ns shares of the ns arithmetic shares by a value based on the first compression factor ? and the masking scaling factor ?1; converting the ns scaled arithmetic shares to ns Boolean shares; right shifting the ns Boolean shares based upon the masking scaling factor ?1 and a second compression factor ?2; XORing an output mask ?2 with the shifted first Boolean s

Abstract: This invention relates to novel annellated carbamyl-aza-heterocyclic compounds that are potential physiologically active compounds (agonists, antagonists, and receptor modulators, enzyme inhibitors, oncolytics, antibacterial and antiparasitic agents, and so on), to a focused library comprising annellated carbamyl-aza-heterocyclic compounds, a pharmaceutical composition comprising annellated carbamyl-aza-heterocyclic compounds as the active ingredient, and to methods of producing and using the same.
