Abstract
An elliptic curve encryption method includes determining a window size indicating a number of groups for performing scalar multiplication in parallel, generating, based on a first encryption key, a second encryption key, the generating the second encryption key including changing a value of the first encryption key, the first encryption key being a random number, generating a third encryption key based on the second encryption key, the generating the third encryption key including changing a total number of bits of the second encryption key to be a multiple of the window size by applying a binary number-based value conversion method, and performing, in parallel, a scalar multiplication operation with the third encryption key and a vector on an elliptic curve based on the window size, wherein the second encryption key has a value conforming to the binary number-based value conversion method.
