Prof. Paar I don't have the words to thank you enough for these lectures. I took Crypto as an optional module during my conversion MSc in Computer Science and I felt quite challenged/intimidated by the content. Your lectures helped me enormously and I felt very confident for the final exam where I ended getting a first class mark in a difficult examination. Thank you so much once again!
Before and After graduating from my school up to now that am doing my Masters in Information Security, I had never ever attended such lecture from any professor in my entire life, It was really, really AWESOME. I really liked that due to the one who is giving lecture have a good knowledge of the topic, Huge love and thanks from Afghanistan, for sharing such lectures.

Dear Professor Paar, This is my third lecture. I am so impressed with your series, and teaching style that I plan to go through the series. I have even bought your textbook. I am surprised that you did not talk much about the important historical implications of Crypto - the disastrous Zimmerman Telegram in 1917, Enigma, the British poem codes of WWII - that were so easily broken by German cryptanalysts - or the reuse of Soviet one-time codes, which led to revelations about the Soviet spy networks in the US and Britain. While you mention Enigma In your lecture, you don't even mention military or intelligence communication in the use of Crypto. During the war, my father (who had studied in Germany) was in charge of a US Army mobile crypto unit which was tasked to decrypt Wehrmacht radio traffic. The ciphers were changed daily. A Luftwaffe weather plane out of Norway broadcast the weather parameters from the North Pole every morning. The Allies sent a plane up to the North pole to get exactly the same information. Comparing the ciphertext to what was likely to be the plain text, it took my dad's cryptanalysts less than 20 minutes to break the cipher. This was so reliable that when the American Air Corp offered to shoot down the German weather plane, they were persuaded not to do so because of the value of the daily reports to the Allied cryptanalysts.. Thank you for your excellent lectures. I love that you break into German sometimes, and even quote Goethe!

That's interesting -- but it sounds very military-oriented. Might be a good idea for a lecture series on 20th-century military cryptography (don't military academies teach that? I'm not sure). You seem to have a lot of info on the subject, maybe collect more facts on the topic and present it to a lecturer or post it on a blog? It could be a great way for non-CS-students to be introduced to cryptography in a historical context. On Khan Academy, the lecturer sometimes goes into cryptographical history, but also gives visual examples of cryptography (as in, how some basic methods affect pixels in an image). It's a nice change from the usual dry crypto lecture (not talking about Paar's -- his series is great, was recommended to me by a fellow student).

I am a Computer Science graduate, currently planning to study abroad, specially in Germany or any other EU state. I always loved the cryptography, and once I learned about DES, and AES, they just blew my mind, and I love the diffusion they cause. I stumbled upon the 7th Lecture of AES, as Galois Fields were a bit of a mystery for me. That just hooked me up, and now I will watch the whole series IA.

Another important reason to make your cryptography public, is for obscuration. If you were the only group using that specific cryptographic method, it would be easy to identify your specific messages. This is why the TOR Project was made public. It was invented by the US Navy, but was then made available to the public, in order to obscure their messages. For example, if another country was doing traffic analysis, it would be easy to identify US Navy messages, if the US Navy was the only group using TOR. Now that millions of people are using it, it has become much harder to identify traffic, from any specific source.
