Channel
Bob
Sender · Trusts the Channel
Believes he is sending a message directly to Alice. Has no indication that the data path between them is being observed.
Eve
Adversary · On-Path Attacker
Sits silently between Bob and Alice on the network. Captures a copy of every packet that crosses the wire, then forwards the original so neither party suspects interception.
Alice
Receiver · Trusts the Sender
Receives the message and assumes it traveled directly from Bob, untouched. Confidentiality has already been broken before delivery.
