Abstract
An Algorithm is considered computationally secureif it can not be broken with standard resources, either currentor future. In this paper we have introduced a new block cipheralgorithm named X-MODDES. It is unique independentapproach which uses several computational steps along withstring of operators and randomized delimiter selections byusing some suitable mathematical logic. X-MODDES isspecially designed to produce different cipher texts by applyingsame key on same plain text. Thus a new protocol has been ....etc

Abstract
To encrypt a text _le and to decrypt the encrypted form of the _le to get the original input text _le. This encryption and decryption is done using the most widely used private key encryption scheme based on data encryption standard (DES) adopted in 1977 by National Bureau of Standards.It was designed by IBM based on their own Luci_er cipher and input from NSA.For DES, data are encrypted in 64-bit blocks using a 56-bit key. The algorithm transforms 64-bit input in series of steps into a 64-bit output of cipher text. The same steps, w ....etc

Data Encryption Standard (DES)
• Financial companies found the need for a cryptographic algorithm that would have the blessing of the US government (=NSA)
• First call for candidates in May 73, followed by a new call in August 74
• Not very many submissions (Why?)
– IBM submitted Lucifer
• NSA worked with IBM in redesigning the algorithm
DES
• DES became a federal standard in November 76
– NBS (NIST) hardware standard in January 77
– ANSI X3.92-1981 (hardware + software)
– ANSI X3.106 ....etc

Performance Analysis of SAFER+ and Triple DES security algorithms for Bluetooth Security Systems
Abstract
In this paper, comparison of the SAFER+encryption algorithm and Triple DES algorithm forBluetooth security systems is done. Performance of theabove security algorithms are evaluated based on theefficiency of the algorithm. The whole design wascaptured entirely in matlab. In order to check theefficiency of the algorithm, noise is being added to theencrypted data and the output is seen to be obtainedwithout any incorrectness which ....etc
