Centralized Server Controlled Secure Packet Transmission in Military Network

Abstract

The development of a novel wide-area centralized damping controller to improve the time consuming in presence of time-varying delay and packet dropout in the communication network. Two different strategies have been adopted to deal with the input and the output delays. In the first strategy, the system output delay has been compensated by predicting the packet drop. In the second strategy, a wide-area controller, based on delay-range-dependent stability criteria, has been designed for the timevarying delays in packet loss. In a large network file transfer between two nodes experience lot of challenges. There is minimum safety in file transfer between two source and destination. Malicious users and hackers will steal the data easily, the user may never know the data being transmitted in a secure way. Hence a Centralized Controlled Secure Packet Transmission is introduced. Here centralized server provides packet to the source node (Soldier) for encryption and it provides the key for the destination (Military Chief) for decryption. The centralized server also tells to the source, through which intermediate server, the encrypted file can be transmitted to the destination.
