Introduction :
These days internet is being used by people of different walks of life, who are facing more challenges in terms of data storage and transmission which in turn increases number of users in the network thereby considerably. In the advanced world, information is more essential of workstation interchanges and heart of worldwide economy. To guarantee the security of information, the idea of concealing has pulled in individuals to present an imaginative and innovative answers for secure information from falling into wrong hands. The dissemination of advanced media confronting an issue from numerous years as the information are struck and controlled by unapproved individual. The web is a strategy for correspondence as a method for appropriates data to the masses. As an effect of spreading the web around the globe, stowing away of secret messages through distinctive techniques is expanded. Step by step the data concealing strategies are expanding with more complex methodology. Pictures, features, content and so on are utilized within correspondence of mystery messages in advanced media.
steganography and cryptography are distinctive sorts of strategies utilization to send secure information transmission. Steganography is the craftsmanship and art of concealing information into distinctive bearer records, for example, pictures, features, sound, content and so forth. In cryptography, there is parcel of degree to discover mystery message that we send by outsider (assaulter). Anyhow in steganography discovering mystery message is not that much simple. In this way, that just the sender and beneficiary realize that the message even exists. It doesn't pull in unwanted consideration. The mystery message that sender exchanges over the system, might be encoded and covered up into TCP/IP header utilizing Stego object. The Stego article is an encoded message inserted into transporter document, for example, pictures, feature, sound, content.
steganography, which is otherwise called "stego," is the act of concealing a message in an alternate medium. For example, a message could be stowed away in a picture document, where the consideration of a message—scattered all around the picture is unrealistic to be recognized by somebody seeing the picture. In steganography, a message could be covered up in a picture, a sound record, a feature cut, or other human-read medium where the consideration of the message will prepare slight varieties that may not be recognizable. Messages can additionally be stowed away in a record's slack space and different spots where others may not look.
An exemplary case of content based steganography is a composed message that was sent to a con- demined detainee, a Sir John, a Royalist throughout a common war in England. The message to the detainee seemed, by all accounts, to be a meandering letter, yet the third letter after every punctuation imprint structured a mystery message, which gave the detainee a profitable...

585 words - 3 pages multicast routing protocol according to distance from source to destination in a network. Security is a more sensitive issue in MANETs than any other networks due to lack of infrastructure and the broadcast nature of the network. While MANETs can be quickly set up as needed, so they also need secure data transfer over the network. We provide encryption and decryption algorithm using Rijndael (AES) block cipher. It helps the message to secure while data transfer using multicast routing protocol.
