The courses by Boneh and Katz on Coursera are different. The Boneh course is excellent.

Note that your question covers a huge amount of ground! If you could be more precise in the kinds of applications you are looking for. For example, your question suggests you are more interested in public key methods.

I guess that's a sign of my ignorance on the subject. But yes, I'm mostly interested in public key methods.

Have you looked at a textbook like Goldreich's Foundations of Cryptography?

# Reference on cryptography methods

(Asked by: username_0 on 2015-01-22)

I'm looking for a good reference, possibly a survey, on the different types of cryptography methods. As far as I understand, the security of a cryptographic method depends on some hardness assumptions, and I've heard of methods based on the hardness of factorization, discrete logarithm, NP-complete problems (such as the Knapsack problem) and problems on lattices.

Is there any good text addressing the different existing paradigms?

In particular, I would be interested on open problems and questions on less studied methods.

Answers for this question may include both references to a text giving an overview of the area but also to specific methods.
