  3. 3. Motivation● Recently we have a generation of people more and more dependent on information technology but many of them dont have any idea about risks involved on it.● Facebook, Cell Phones, Notebooks and any others are able to store data digitally.
  4. 4. What is it?● Cryptography is the science of using the math to encrypt and decrypt data.● In my own words, Cryptography is the study of techniques to ensure the integrity, confidentiality and authentication.
  5. 5. How does it work?
  6. 6. How does it work?● All means of cryptography are based on intractability of a problem mathematics● The most famous are whole number or the discrete logarithm problems.● Both methods are efficient.
  7. 7. A brief history.● The earliest forms of secret required nothing more than a piece of paper and writing as a much of people couldnt read.
