WebNow, when it comes to Diffie-Hellman, generator is used in two slightly different meanings (and that may be what is confusing you). In the first meaning, a "generator" is defined to be an element that generates the entire group. That is, when we talk about DH (and thus the group Z p ∗ ), we say that g generates the entire group means g k mod ...
