TomteHas been announced and cancelled many times, but I'm hopeful this time, because I could actually enroll, and there was a pre-course survey a few weeks ago.
Looks to me like it's seriously starting in four months now.
calvinsPushed back for another six months yet again. So much for the idea somebody here put forth that it always gets cancelled in the middle of the previous month if it's going to get cancelled. This time it's four days before it would have started.calvinsI know there are quite a few readers of HN that have been waiting for Crypto II for a while, so consider this a public service announcement.
Dan Boneh's "Introduction to Cryptography".
Dan Boney is awesome. I really like that he is sharing his classes and materials online (I would highly recommend his classes in Stanford and his coursera class as well). I think this is still a work in progress / draft so don't expect to have an ebook available yet.

Is this the course you are looking for? https://www.coursera.org/course/crypto2
Does anyone know how this compares to Coursera course  or  + ?
Both coursera and udacity have amazing courses on crypto.
Coursera crypto I: https://www.coursera.org/course/crypto
Coursera crypto II: https://www.coursera.org/course/crypto2
I took coursera crypto I myself. It was a lot of work, but I learned a ton.
midas007Crypto I was very well put together, Crypto II has a high threshold to maintain 
References:ropman76Crypto I is great course and I recommend to anyone one who wants to know more about how crypto works.
I'm taking Stephen Boyd's Convex Optimization: https://class.stanford.edu/courses/Engineering/CVX101/Winter...
This class was one of the early courses with online videos and materials. I think this will be great if you are interested in learning about convex optimization in some detail. This class will be on Stanford's OpenEdx platform with new materials.
The practical exercises in part I worked through defects in the implementations of cryptographic protocols. If you want to really understand how some of the popular crypto algorithms work, these two courses will help you.
Try Dan Boneh's crypto course on coursera . It covers quite a lot of ground, both practical and theoretical, and includes programming exercises similar to the matasano puzzles. Without a doubt it's one of the best courses of the dozen MOOCs I've taken. There's also a followup course  (I haven't taken it yet personally, but I believe the currently scheduled run will be the first).
Interestingly enough, there's also an upcoming security course (with no date planned yet) which will cover the application programming part of security and will be co-taught by him. 
Wow. I'm even happier to have completed it then!
Agreed, it was a great course. Looking forward to the sequel in early April. https://www.coursera.org/course/crypto2
