Let the users be named Alice and Bob. First, they agree on two prime numbers g and p, where p is large (typically at least 512 bits) and g is a primitive root modulo p. (In …
WebNov 24, 2014 · Following the usual steps of Diffie-Hellman, Alice and Bob should each select integers a, b between 1 and p-1 and calculate resp. A = g a and B = g b. To brute force this, an attacker should expect to try all possible values of a (or b) between 1 and p-1 until he finds a value that yields A (or B).
