1. Alice and Bob

   Alice and Bob are two commonly used placeholder names. They are used for archetypal characters in fields such as cryptography and physics. The names are used for convenience; for example, "Alice sends a message to Bob encrypted with his public key" is easier to follow than "Party A sends a message to Party B encrypted by Party B's public key." Following the alphabet, the specific names have evolved into common parlance within these fields—helping technical topics to be explained in a more understandable fashion.

1. Alice and Bob

   The archetypal individuals used as examples in discussions of cryptographic protocols. Originally, theorists would say something like: “A communicates with someone who claims to be B, So to be sure, A tests that B knows a secret number K. So A sends to B a random number X. B then forms Y by encrypting X under key K and sends Y back to A” Because this sort of thing is quite hard to follow, theorists stopped using the unadorned letters A and B to represent the main players and started calling them Alice and Bob. So now we say “Alice communicates with someone claiming to be Bob, and to be sure, Alice tests that Bob knows a secret number K. Alice sends to Bob a random number X. Bob then forms Y by encrypting X under key K and sends Y back to Alice”. A whole mythology rapidly grew up around the metasyntactic names; see http://www.conceptlabs./definition/alicebob.In Bruce Schneier's definitive introductory text Applied Cryptography (2nd ed., 1996, John Wiley & Sons, ISBN 0-471-11709-9) he introduced a table of dramatis personae headed by Alice and Bob. Others include Carol (a participant in three- and four-party protocols), Dave (a participant in four-party protocols), Eve (an eavesdropper), Mallory (a malicious active attacker), Trent (a trusted arbitrator), Walter (a warden), Peggy (a prover) and Victor (a verifier). These names for roles are either already standard or, given the wide popularity of the book, may be expected to quickly become so.
