@alice Trudy for "Intruder". :-) I have heard Mallory, but never Eve.
Elsethread, I mentioned an anecdote: A long time ago I needed to buy some time to gather my thoughts during an exam about applied cryptography, so when I drew that diagram I introduced them as Anthon and Berg, with Toms listening in.
