Underwater communication can be used for collecting data of undersea ecology, secure naval area, pre alarm for natural disaster etc. Most of the surface in our world is surrounded by water; for this reason underwater communication can be hugely beneficial for us. However, secure the network and its database is a big challenge as this kinds of network is being setup remotely; far away from human touch. In this paper, we have introduced a new model of secure communication system which will secure the network and its database using AES secret key generation algorithm and node key.50 pagesenBrac University theses are protected by copyright.
