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.
