Ahh cryptography, still finding which is the best video to clear up your understanding of Needham & Schroeder protocol? Well, look no more, here is mine in less than 8 minutes. I always thought I’m going to fail this class because from what I heard from my seniors is impossible to pass or ace this subject. I was so stressed and focus on the first week of this class, throughout this first week, and my first assignment hand out, I tell myself this ain’t that bad. Is actually an interesting subject if you give yourself time to digest.
