An Intrusion Detection System for Secure Distributed Local Action Detection andRetransmission of Packets

摘要

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