Sobre o curso

Cryptography is an indispensable tool for protecting information in computer systems. In this course you will learn the inner workings of cryptographic systems and how to correctly use them in real-world applications. The course begins with a detailed discussion of how two parties who have a shared secret key can communicate securely when a powerful adversary eavesdrops and tampers with traffic. We will examine many deployed protocols and analyze mistakes in existing systems. The second half of the course discusses public-key techniques that let two parties generate a shared secret key. Throughout the course participants will be exposed to many exciting open problems in the field and work on fun (optional) programming projects. In a second course (Crypto II) we will cover more advanced cryptographic tasks such as zero-knowledge, privacy mechanisms, and other forms of encryption....

Great course, thank you!

This is a great introduction to Cryptography. Before this course, I was a complete beginner and now I am reasonably comfortable with the basics. I am definitely planning to take Cryptography II sometime in the near future.

One comment - working full time and taking this class was not easy. For future classes, it might be easier if you make each week less packed, possibly even splitting each week into 2 weeks. This would make it easier to keep up with the schedule.

This course is the Α and Ω about Cryptography and Security. It provides a very thorough overview of the basics of Cryptography from a theoretical point of view, albeit including including real life examples. Definitely recommended even for persons already familiar with cryptographic or security concepts. Professor Boneh is extremely illustrative and provides his expert knowledge in a very practical manner. I sincerely thank you for the amount of knowledge provided in this course!

This is a fantastic introduction to the world of cryptography! You learn about the basic concepts of encryption, authentication, authenticated encryption, public and private keys and the underlying mathematical principles that (should) make it hard to break the ciphers! You also learn about historical developments, real world applications and current challenges that would bring you instant fame in the crypto world. Also it is not a disadvantage if you really love solving puzzles!

I'm the Technical Director of an electronic company. I didn't know very much (certainly not enough) about cryptography, except some vague general information. My company needed to gain first hand knowledge to protect a new line of products, for which online reprogramming will be necessary. This crash course about cryptography has been extremely enlightening, to address the development of these procedures.

Thank you Dan for your good work and carry on with it.

Este curso, ministrado pelo grande professor Dan Boneh, é maravilhoso, para dizer o mínimo. Mostra a teoria didaticamente, de forma a facilitar a matemática do assunto que é bem árida, mas também introduz aspectos práticos importantes para quem milita na área em particular com especificação e desenvolvimento de software. Os exames, para além de simples avaliação do aprendizado, foram ótimas ferramentas para fixar e melhorar o entendimento do conteúdo.

Прекрасно структурированный курс. Практические задания (optional), потребовавшие большого количества времени (почти ничего не доделал до конца, но заниматься было интересно, возможно, займусь позже). Тесты строго по лекциям. В целом, всё понятно.

Иногда языковой барьер слегка мешает (термины запоминаются не с первого раза, приходится пересматривать - названия атак и т.п.). В 1 неделе есть презентации с лекций, по ним проще искать материал.

I learned a tremendous amount from this course and it provided the grounding for an array of different areas of infosec studies I am pursuing. I highly recommend it. Many of the ideas were easy and intuitive to grasp, but there is also enough depth that I will likely take the course again at a later date.

The quizzes and projects were thoughtful and challenging, and effectively tested that the student understands the key ideas of material.

The course was authentically cryptic. Just kidding. Once I listened to Prof. Boneh a few time over, I started to get the idea. asymptotic security while never stated as such played a fundamental role in the security proofs. Professor Boneh augmented the notion of correctness to include immunity from side channel (Power and timing attacks). The course was a great medley of pragmatic advice and theory. I am grateful for this class.

Learning Cryptograpy is not a walk in the park as it requires a good understanding of the theoretical foundations and it is so easy to get wrong, yet it is essential for an IT professional to get a good grasp of the subject. This course is invaluable in that respect, the instructor presents the material in a clear, concise fashion without overwhelming with the math involved, giving the overview you need as a professional.

This is one of the best cryptography courses I have seen. Initially, I felt that the course was going faster. So I skipped the course two times after following about two weeks :). But I thought to give another try for the third time. Then I started to get comfortable and understand in time.

I strongly recommend this course to people who are looking to get a better theoretical understanding of cryptographic primitives.

A fantastic, university level course on Cryptography, most commonly referred to as the "gold standard". Personally, I found this course to be extremely helpful and assistive to my learning on the subject. However, I think that this course delves too deeply into the theory of cryptography, I think it would prove beneficial if Dan Boneh ran us through more coding examples or specific realistic use-cases.

Very interesting course where you learn how to analyze cryptographic constructions. I love the way is taught, building on top of basic constructions until you implement real-world systems. I certainly got interested in cryptography many times, but always dropped the courses before the end. This one got me hooked all the way!. The programming assignments were great to assimilate concepts. Well done!

It took to me more than one month and a half to complete this course but it has been a great stimulus to learn fundamental concepts and tools about cryptography. One of the most difficult part has been public-key cryptography mostly due for its base on number theory but now I have a good knowledge of RSA and Diffie-Hellman key exchange protocol. I look forward for the 2nd part of the course.

Excellent in-depth introduction to the field of Cryptography! Absolutely rigorous treatment of the subject, down to every last mathematical detail. I feel like I sat in on a real university course at Stanford, and I believe this experience will help my work, my employer's products and will allow me to look critically at cryptographic code that comes across my desk. Thanks Prof. Boneh!

A truly excellent course. The content is very well done and presented, the problem sets challenging enough and the programming assignments are interesting and really worth completing. Dr Boneh explains all the concepts in a very clear manner and has tons of practical examples to share, which bring to light what can at first sight seem a little abstract. I highly recommend this course.

Amazing course and an outstanding teacher. Worth every penny and minute spent on this one. You learn not just how to build secure systems but also how NOT TO, which I consider even more valuable.The material is explained so fluently you have no doubts about professor's outstanding knowledge of it. This doesn't mean it's an easy course, though, so get prepared for some headache :)

An excellent course to learn the fundamentals of cryptography at a pretty deep level. It includes very well crafted programming assignments and tests. The professor is an expert in the field and very rigorous and precise. The materials are very well crafted and it contains a lot of interesting and useful references for extension. It was quite hard but it was definitely worth it.

Great course. It describes most commonly used encryption algorithms with fun historical examples. Explanations are given from diverse point of views including cyber attack, data protection and computational efficiency. Assignments are challenging enough for people comfortable with computer sciences, probability and number theory and maybe a bit hard for people who aren't.

The course was extremely informative and interesting. I do not possess a computer science background and enrolled in the course just to learn a little about cryptography. While the learning curve was steep, the course content was engrossing that I did not want to stop. Infact, it motivated me to gain more knowledge in the field and I am currently learning programming. :)

This is a great course that was taught well, and had very helpful mentors. In general I found the course challenging but not too difficult. The reward was a good understanding of the open cryptographic protocols that are used in most real world applications. As minimum prerequisites, I would recommend having done courses in statistics, probability theory and programming.

I took the course in 2014, whether you are a beginner in cryptography or a regular practitioner, the course won't disappoint you. Another master class from Stanford. The problem sets and programming assignments are of reasonable difficulty. So if you are planning to take a course on cryptography, this is just the one- comprehensive and up to the expectations.

Thank you Coursera and The professor for such an oppotunity to learn Cryptography.

It's very challenging in the begining but the more i learn the more interesting the subject becomes. Professor Dan Boneh is really great at teaching the materials.

I hope that Cryptography II will be opened soon so that i could further my career in the cybersecurity field.

This course has taught me crypto basics in the best possible way. I am eagerly waiting for the second part to enhance my knowledge about this interesting field. The Lectures and they way questions were formed in quizzes made the learning interesting and benefiting. Best wishes to the instructor and Organizer who arranged and compiled the course material.

Very interesting course! Good, balanced presentation of lecture material. Weekly tests make you think well and study the theory more deeply. Despite the fact that there are few questions in the tests, they are not so simple as not to open the textbook. Later I want to finish all optional programming tasks and read recommended books more carefully again.
