Abstract:
Computer security is very important role for
information and data. Data communication is the most
important in the world. Communication technology is increased
as well as an authorized person can intercept the security of the
system and can get the data. So, computer security is the most
important and must secure our data in communication. In this
system, man-in-the-middle attack, in which the adversary
inserts, deletes, or arbitrarily modifies messages sent from one
user to another by using Diffie-Hellman key exchange
algorithm. To prevent this man-in-the-middle attack, station-tostation
protocol can be used. STS protocol is a cryptographic
key agreement scheme based on classic Diffie-Hellman.
