When my wife’s aunt and uncle (Alice and Bob) had a daughter it seemed obvious to to me they should name her Carol. They failed to see my logic, however.

How can we be sure that this message comes from the real Eve? Maybe it comes from Alice…

And if they had a son he should be named Ted?

“””How can we be sure that this message comes from the real Eve? Maybe it comes from Alice…”””

How very astute, and here’s proof:

” … to the lipstick heart smeared on the disk … ”

Obviously this is not Eve the eavesdropper, it’s Ivan the Interceptor working with Paul the Pretexter!

Good heavens! Now that’s gotta be the most significant recognition of an arcane discipline I’ve ever seen.

Congratulations (I think).

I wonder what would be done if a cryptographic protocol requires 5 participants.
Would Eve come to late honors? Would we meet Fred?
Or won’t it be necessary to have such a protocol as any 4-party protocol can be extended to 5 participants? I think so, but I don’t remember that this topic would have been adressed anywhere.

“I wonder what would be done if a cryptographic protocol requires 5 participants. Would Eve come to late honors? Would we meet Fred?”

In Applied Cryptography, I continued the sequence: Alice, Bob, Carol, Dave, Ellen.

Eve is reserved for the eavesdropper.

COOL!
The cryptography is serious bussines.
