Appearing in the seminal paper by Diffie and Hellman, the first published public-key algorithm that defined public-key cryptography [DIFF76] is referred to as the Diffie-Hellman key exchange (Stallings & Brown, 2008, p. 641).
•Define the Diffie-Hellman key exchange? How is this information relevant to you?
•What is the purpose of the algorithm? Be specific.
•How does it work? Give an example from personal experience or one that you have read about.
•What would be an appropriate implementation in an organization for the algorithm?
•In what types of organizations would this be appropriate?

Diffie-Helman key exchange is about creating a common key to be used in the communication process and not about actually sharing secret information. It must be seen as preparation phase of a secure way for communicating between two parties in order that an eavesdropper can't obtain the key. This means that even if the traffic is somehow captured, it is virtually impossible to be decrypted....
