Port Knocking C++ Computer Science Project with Report

Introduction to Port Knocking C++ Project:

The Port Knocking is the communication system in the host to host where the data transfers from one closed port to another closed port. The port knocking process posses the different variants, the information can be encoded as the Port sequence or the Packet payload. Normally, the data transfers to the closed ports which is arrived to the testing host or monitoring daemon that cross checks the information by not sending the acknowledgement to the sender. 

The Port Knocking is the process of communication with in two or more computers or the client and the server where the information is encoded and encrypted in the chain of the port numbers. The chain or the sequence encoded and encrypted is called the Knock. t The work of the server is to monitor the client’s requests for the connections. The server will not provide the ports initially. The client requests connection trials to the server and send the SYN packets for the mentioned port present in the knock. So it is named as the Port Knocking. The server initially will not answer to the client knocking stage or requests. The server actually processes the port sequence or the monitoring of the SYN packets. The server first decodes the requests of knock and the then allows the client. 

However the authorized users are allowed on the firewall, the closed ports are available for the other users. Our Project is to find the ways of authentication service and found the Port Knocking. The Project considers the existing system and implemented the modification of the existing system by using of the novel port knocking architecture and introduces the high authentication service and highlighted the demerits of existing system. 

The Proposed System 

1. The Port Knocking gives the highly secured authentication and the information transmission to the host without considering of the ports.
2. The client is not aware of the server is performing the knocking sequence decoding.
3. The server monitors the client request.
4. The port is available to the requests for the specific time.
