This communication of critical information over global computer network needs encrypting the digital information before transmitting through the network. In this paper, a novel idea is proposed for a discrete chaotic data encryption/decryption algorithm using Lorentz attractors. The encryption system consists of a chaos generator, which takes the input message as the plain text and produces an independent output message known as cipher text. In the present approach the data to be transmitted is digitally modified by the chaotic system to produce the cipher text, which is sent through the transmission medium and the reverse process occurs at the reception end to decrypt the data.
