Other Courses

Dan Boneh has two excellent on-line cryptography courses: Cryptography I and Cryptography II. They cover many of the same topics as my course, but with more theoretical depth.

Bryan Pendleton wrote a comparison, Comparing the Coursera and Udacity Cryptography classes, which I think is fair and helpful (and positive about both courses).

If you've already taking my course and want to go in more depth and gain a more formal understanding of cryptography, I highly recommend taking Dan Boneh's course next.
