WebI'm trying to understand how to multiply a point by a scalar to get a point in elliptic curve cryptography. Here's an example from my textbook. The group is E 257 (0, -4). That's shorthand for y 2 = x 3 + 0 x - 4 (mod 257) According to the book, 101 (2, 2) = (197, 167) How can I get from 101 (2, 2) to (197, 167)?
