Paul, Alice

Paul and Alice are commonly used names in cryptography and computer science to illustrate secure communication concepts. They represent two parties who want to exchange information privately. Paul wants to send a message to Alice without an eavesdropper understanding it. Techniques like encryption (converting messages into unreadable code) and sharing keys (secrets needed to decode messages) are used. These examples help explain how secure communication protocols work, ensuring that only Alice can read Paul's messages, even if someone intercepts them.
