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

Space Theaters
The pace at which space is being exploited and explored is at present slowed by the cost of launching payloads. Typically, a payload will be placed by a rocket into low-Earth orbit (around 400 km), and then be boosted higher by rocket thrusters. But just transporting a satellite from the lower altitude to its eventual destination can run to several thousand dollars per kilogram of payload. To cut expenses, space experts are reconsidering the technology used to place payloads in their final orbits.

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

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
