%0 Journal Article %T SD-AREE: An Advanced Modified Caesar Cipher Method to Exclude Repetition from a Message %A Somdip Dey %J International Journal of Information and Network Security (IJINS) %D 2012 %I Institute of Advanced Engineering and Science (IAES) %R 10.11591/ijins.v1i2.436 %X In this paper the author presents a new cryptographic technique to exclude the repetitive terms in a message, when it is to be encrypted, so that it becomes almost impossible for a person to retrieve or predict the original message from the encrypted message. In modern world, cryptography hackers try to break a code or cryptographic algorithm or try to retrieve the key, which is needed to encrypt a message, by analyzing the insertion or presence of repetitive bits / characters (bytes) in the message and encrypted message to find out the encryption algorithm or the key used for it. So it is must for a good encryption method to exclude the repetitive terms such that no trace of repetitions can be tracked down. For this reason we apply SD-AREE cryptographic method to exclude repetitive terms from a message, which is to be encrypted. SD-AREE is a modified Caesar Cipher Technique along with advanced bit-manipulation cryptographic method. In SD-AREE method the repetitive bits / characters are removed and there is no trace of any repetition in the message. %U http://www.iaesjournal.com/online/index.php/IJINS/article/view/436
