Today is the world of computers. Everyone is dependent on computers for communication. So communication threats are increasing day by day. Traditional means of communication without security has become vulnerable. So, a secured communication is necessary.

In our system, we have included many security mechanisms which can guard our transmitting data from all the security attacks. By using Digital signature we can protect our system from the most serious attack, denial of service that can’t be eliminated by ordinary means. In addition Digital signature provides Authentication and Integrity to the data. Whereas Encryption provides Confidentiality. These Security mechanisms guarantee the safe communication.
