Comic: Public Key Cryptography in a fairy tale!

The comic shown above shows a PKC scenario of a commonly known fairly tale "The Frog Prince". This was done by a group of ten people including me. Try and see whether you can understand it!! :) (click on the image to see it in original size (obviously)!)

HINT: This involves a Witch, a princess, and a frog (prince), and this shows the encryption scheme of PKC.

This comic was done as a requirement for the "Computer Security" module in my department, Dept. of Computer Science & Engineering, University of Moratuwa.


  1. OK, The witch turns the prince (Plain text Payload) into a frog (Encrypted Payload) with her spell (public key of the princes) and send the frog to the princes. Princes's kiss (private key) turns (decrypt) the frog back to the prince (Plain text payload)
