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!

I put youtube on autoplay, and woke up to this lecture...it's quite informative

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.

Great lecture! Approximately 2 hours ago i had no clue such lectures on topics like these even existed! But for the part 1 hour 17 mins it feels like I've attended a lecture on cryptography! I feel great! Tomorrow or day after another lecture (Thumbs Up) !!

Learn Cryptography from a German guy, how cool is that?

You're the best thing that has ever happened to the U.S.'s education system!! thanks for saving many student's lives, sir!

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!

So, I downloaded a book for teaching me cryptography yesterday and I woke up today searching for a lecture and surprise surprise, it's the same man who wrote that book . The way he teaches has impressed me more than the book. Thanks.

I'm Iraqi software engineering student in the last year, I have much interest in cryptography, these lectures will be useful to me 😊

[robberywills]

looking at this video really gives me the motivation I need for school. Honestly, thank you for this video.

After this lesson, fell in love with Cryptology. Thanks for educating us!

Thanks mr christof for releasing this lectures on a platform like this where we can stream free.

I am following from Cameroon.
You inspire me Alot. Working hard to be like you.🙏

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.

i used to attend prof christof Paar's lecture once at RWTH Aachen, , he talked about how to decrypt satellite phone which was one of this students work .... so amazing... and I am still watching his 24 playlist lectures till now a day :) thanks Prof Paar

[Integralsouls]

10 freaking years but still the best lectures on cypt. on u tube

[anusaxena]

Professor Paar, thank you so much for making these extremely interesting lectures. Your lectures make crypto ' within reach' !! In addition you sound a very brilliant person !!

Dear lord, this is a university lecture not a French new wave film, what is with this unsteady camera?!
