Abstract
An elliptic curve cryptography method which generates a public key for use in a communication encryption using an elliptic curve, including: changing a number of a secret key (d) of (k) bits to an odd number; encoding the secret key to yield an encoded secret key (d) in which a most significant bit (MSB) is (1) and a rest positional number is (1) or (−1); and computing the public key (Q=Dp) by multiplying the encoded secret key (d) by a predetermined point (P) on the elliptic curve by a scalar multiplication.
