Decrypting Cryptography

Aishwarya Seth (~aishwarya75)


One of the most important aspects of cyber security has always been cryptography and yet I have come across few people working in this field. Through my talk, I would like more people to get to know about this field and give them a simplified overview of what cryptography is and what all can be done using cryptography. I will be explaining all the topics using maths and python codes as much as possible.

  • Introduction [3 min]
  • Classical Cryptography [5 min] : Monoalphabetic substitution cipher, Polyalphabetic substitution cipher, Transposition Cipher etc.
  • Modern Cryptography [5 min] : Brief of operations and mathematics used like xor operation and modular arithmetic
  • Symmetric Cryptography [7 min] : DES, 3DES, AES etc.
  • Asymmetric Cryptography [5 min] : RSA, Diffie Hellman, Digital Signatures etc
  • Q&A [5 min]


Not necessary but good to have some knowledge on:

  • Basic python
  • Basic algebra
