Webp should be a prime number, but g has to be a primitive root (otherwise known as a generator) mod p. Remember that if we apply the exponents 1 to n-1 on a generator, g, it will produce the values 1 to n-1 (but not in order). e.g. we could use p= 13 and g = 6 6^1 mod 13 = 6 6^2 mod 13 = 10 6^3 mod 13 = 8 6^4 mod 13 = 9 6^5 mod 13 = 2 6^6 mod 13 = 12 Web1 With primitive roots A primitive root, modulo p, is a number with the property that the list ; 2; 3;::: contains all the numbers 1;2;:::;p 1 (modulo p).
