In this paper, we present a novel encryptionless algorithm to enhance security in transmission of data in networks. The algorithm uses an intuitively simple idea of a “jigsaw puzzle” to break the transformed data into multiple parts where these parts form the pieces of the puzzle. Then these parts are packaged into packets and sent to the receiver. A secure and efficient mechanism is provided t...
