On September 7th, 2022, the directors of the
computer club at DPS-Modern Indian School— Keren John, Varshaa
Balasubramanium, and Sushrut Patil—conducted an educational
workshop on "Cryptography". The session began with an
introduction to the field of cryptography and code-breaking,
followed by an explanation of its significance in both the past
and today using real-life examples and historical events
This was followed by a lesson on encryption and decryption where
the students learnt how to encode and decode messages using the
shift cipher, substitution cipher and permutation cipher and
learnt the advantages and drawbacks of each.

|
| Succeeding this, the students were introduced
to the breakthrough in the world of Cryptography in World War II
as they learnt about the working of ‘The Enigma’, a machine used
by Nazi Germany for sophisticated encryption, and the efforts
and successes of Alan Turing in breaking codes encrypted by this
machine. They also grasped the concept of ‘Brute Force Attack’
used in many current day applications. |
|
| The meeting ended on a high note
with an interactive Q/A session for the members where they all got to
encapsulate the decrypting methods learnt during the session. |
