The Telegraph, telephone, radio, and especially the computer have put everyone on the globe within earshot----at the price of our privacy. It may feel like we are performing an intimate act when, sequestered in our rooms and cubicles , we casually use our cell phones and computers to transmit our thoughts , confidences, business plans, and even our money. But clever eavesdroppers , and sometimes even not-so-clever ones can hear it all. We think we are whispering , but we really are Broadcasting !!!!

A potential antidote exists: CRYPTOGRAPHY , the use of secret codes and ciphers to scramble information so that it's worthless to anyone but the intended recipients. And it is through the magic of cryptography that many communication conventions of the real world--such as signatures, contracts, receipts, and even poker games--will find their way to the ubiquitous electronic commons.

Crypto Group @ NSF aims at giving a general overview of the field, combining impeccable history and intriguing stories of espionage and intellectual breakthroughs from Ancient Egypt to the age of the Internet, from Atbash to Enigma and from Enigma to AES and RSA thererby insisting on the various cryptographical questions one has to address, and on the theoretical and practical problems arising from using them. We don't intend to scare people by Hi-Fi Maths , instead we aim at  combining practicality and Understandability with a more meaty level of technical analysis. People who are interested in the History of Cryptography and Cryptanalysis along with the Know-Hows of currently used techniques should look forward to joining this Group  {041 / 010 }
