摘要：In this paper a new approach for message encryption using the concept called deceptive text is proposed.In this scheme we don�t need send encrypted plain text to receiver, instead, we send a meaningful deceptive text and an encrypted special index file to message receiver.The original message is embedded in the meaningful deceptive text.The positions of the characters of the plain text in the deceptive text are stored in the index file.The receiver decrypts the index file and gets back the original message from the received deceptive text. Authentication is achieved by verifying the hash value of the plaintext created by the Message Digest Algorithm at the receiver side.In order to prevent collision attcks on hashing algorithms that are intended for use with standard digital signature algorithms we provide an extra layer of security using randomized hashing method.
