hi........ i need ideas for paper presentation on cryptography....please suggest me idea..

Read some papers on cryptography. What is interesting or important in what you learned? Can you think of some other way to do something that was discussed?

Think outside the boundaries: Would steganography work better than or be better in conjunction with other techniques? What's wrong with sending messages by motorcycle? Do you know about some of the recent work on "spooky action at a distance" paired symmetric particles?

How can you make powerful cryptographic techniques easier for everyday use? How can you convince people it is worth doing? Why would it not be worth doing? Is there a cost/benefit paper to be written?

Are there legal or political issues with cryptography? (What has happened with RIM phones in Saudi Arabia and India recently?)
