Transposition cryptography algorithm using tree data structure

In the way of increasing use of internet exponentially when the message is transferred from sender to receiver over the network, the attempt can be made by the hacker or cracker to break and expose the actual message. So security of message is important issue. Encryption process plays a vital role in maintaining the confidentiality of the message being transmitted over the network. In this paper existing transposition techniques of encryption is discussed. An attempt is made to present a new encryption, decryption algorithm on transposition cryptography algorithm for block cipher using tree and other data structure approaches.
