  1. The Security of Quantum Cryptography

  2. Vasil Penchev, Assoc. Prof., PhD vasildinev@gmail.com http://www. esnips.com/web/vasilpenchevsnews Institute for Philosophical Research, Bulgarian Academy of Science

  3. My story has three heroes This is Alice Alice has a message to Bob

  4. And here is Bob He's looking forward to Alice's message!

  5. But this is Eve! She's eavesdropping!

  6. Both Alice and Bob know that Eve's eavesdropping them!

  7. "I love you!" This is Alice's secret message But Eve mustn't know!

  8. "I love you!" Eve not to understand, Alice encripts her message

  9. "I love you!" For encrypting Alice uses a chipher

  10. Her cipher is a "one-time pad" Each message is encrypted differently

  11. The inventors of BB84 QKD protocol

  12. an IBM Fellow at IBM Research Charles H. Bennett

  13. Founding Director, Institut transdiscip-linaire d’informatique quantique (INTRIQ)Canada Research Chair in Quantum Information processingUniversité de Montréal Gilles Brassard

  14. Department of Applied Mathematicsand Theoretical Physics A better approach pioneered by Paul Townsend University of Cambridge

  15. A better approach pioneered by Paul Townsend

  16. (based on the classic tale of Pyramus and Thysbe) “Quantum Love Story”byCharles H. Bennett

  17. Leigh Trapnell Professor of Quantum Physics, DAMTP, University of Cam- Bridge, Fellow of King's College Artur Ekert

  18. QKD on the market

  19. For encrypting Alice has used a QKD chipher

  20. Now Bob knows Alice LOVES him Eve knows nothing Alice knows Bob knows

  21. All are happy!!!

  22. HAPPY END!

  23. Long Live Quantum Cryptography! Turning Ends into Happy Ones!

  24. Thank You for Your attention!
