Disclosed are an elliptic curve point multiplication operation method and apparatus. The elliptic curve point multiplication operation method comprises ordered point multiplication and point addition operations. In a point addition operation process, when scanning that a current bit of a scalar K is not 0, a true point addition operation is executed, and when scanning that the current bit of the scalar K is 0, an equivalent point conversion operation is executed; the result of the true point addition operation and the result of the equivalent point conversion operation are stored in an identical register file, the register file comprising multiple registers. According to the elliptic curve point multiplication operation method and apparatus, side channel analysis and security error attack can be effectively resisted.
