A Wang ,2012 ,cosmos.ucdavis.edu
Public key cryptosystems use a few major concepts and protocols. One of the most important
is Diffie-Hellman key exchange. This is a secure method of exchanging passwords without
letting interceptors know what they are. It is created based on the assumption that every
