Description : The mainstay of this project is to secure data/information that flow across the network. Security refers to the protection of data against the Intentional modification, i.e. loss or damage of data. The Network security is guarantees the secure data flow in the network.Confidentialy, Authentication and Data Integrity. Because these three makes a network as secure one. In this project it guarantees i.e. Confidentially, Authentication and Data Integrity. Confidentiality: guarantees that the receiver only knows the original message sent by the sender. Even if the Hackers or Intruders hacks the message on the way, they canâ„¢t understand the original message. Authentication: is the process of checking /verifying the identity of the sender. Authentication technique tries to vary that a message is coming from an Authentic sender and not from an Imposter. Data Integrity: is the process of validating the message that the received message is an unaltered copy of the sent message. In this project we used three algorithms. These are DES, RSA, SHA algorithms. In this project first the original message which is going to be sent in the network that message is encrypted in two ways. One is 3DES encryption and another is RSA encryption these encryptions are done parallely.
Technology Used : Java ,Swing
