An Intrusion Detection System for Secure Distributed Local Action Detection and Retransmission of Packets

摘要

With improved technologies, research has a wide scope for identifying various intruders and providing continuous security to any type of data in a network. Present methodologies are working absolutely well in identifying the intruder and securing their data. In this study, we want to show that a mechanism has evolved where in we can identify the intruder's access to our data and send the alert information to the sender that an unauthorized access has turn out. Once the data is sent through packets it undergoes various steps like Hashing, encryption and comparison of the data concatenated with the data packets sent. Hence, in case of any mismatch an alert message will be sent and after sending the alert message the sender should retransmit the data using different path in the same process and the mechanism continues till the destination node sends an acknowledgement to the sender that sent data and received data is matched. With this mechanism, we can assure that the data will not be steeled by any intruder and hence security can be enhanced. A timer will also be kept for efficient matching of the data packets. If the user doesn't access the data in a mentioned time the session will be expired and hence he should wait till the data is retransmitted again. We tried to enhance the throughput by means of re transmission of lost packets amid information exchange over the predetermined system. We can recognize the loss of packet by the technique of packet synchronization and the destination sends the request for re transmission of lost packets which is called as re-transmission.
