摘要

In this paper we present a Mobile Ad-Hoc Network (MANET) which securely transmits Audio data. Even though studies on network security has been done before, secure transmission of audio has not been given much importance since both audio and Ad-Hoc network are both complex to handle. So some simple and efficient methods are required to encrypt Audio data. We aim to provide double security by encrypting and decrypting the audio at each node in the route using stream ciphering method. Key for encrypting the audio at the transmitter is generated by Fast Anti-Random Approximate (FARA) method. In the Network part, routing is done using the standard DSR routing protocol. Key exchange is done by RSA method. To provide extra security to the key, a node address based cryptography scheme is used. So only authorized nodes can take part in this. All nodes will be preloaded with a key. All these provide strong security to the key and audio data. Even though additional overhead and extra calculations are involved, the system does not show any deterioration in performance parameters like security, delay and throughput from the networks which do not take security issues into consideration.
