  • INSULATING GAS USED FOR ELECTRICAL INSULATION OR ARC EXTINGUISHING BY REPLACING SF6 GAS AND ELECTRICAL DEVICE USING SAME
    Publication number: 20240194372
    Abstract: The present invention relates to an insulating gas used for electrical insulation or arc extinguishing of an electrical device, and an electrical device for insulating electricity using the same. The insulating gas of the present invention, which may replace SF6 gas, consists of a mixed gas of trifluoromethyl trifluorovinyl ether (CF3OCFCF2) and a carrier gas. The insulating gas of the present invention has the characteristics of a low boiling point, high dielectric strength, low toxicity, and a low global warming potential (GWP=1 or less), and thus may replace SF6, and the low global warming potential with no loss of high insulating capacity and arc extinguishing capability may reduce greenhouse gases.

  • CRT-RSA encryption method and apparatus
    Patent number: 9571281
    Abstract: CRT-RSA encryption methods and apparatuses are disclosed. The CRT-RSA encryption method includes: calculating first parameter information and second parameter information used in a modular exponential calculation process based on a modular calculation result of a secret key that is obtained using Euler's phi function with respect to two different prime numbers calculated from the public key; performing a modular exponential calculation with respect to a next block based on calculation information of a previous block, in a block unit divided respectively from the first parameter information and the second parameter information; and calculating an encryption process based on a CRT calculation by using the modular exponential calculation results.
