“Science of Secrecy: Going Public” videos by Simon Singh discourse the history of public key cryptography.

The slides and videos from a great winter school organized by Yehuda Lindell at Bar-Ilan University is a great resource to learn about two-party computation (2PC) and secure multi-party computation (SMPC).

The slides and videos from a great winter school organized by Yehuda Lindell at Bar-Ilan University is a great resource to learn about lattice-based cryptography.

A great talk by Vitaly Shmatikov of University of Texas at Austin, on anonymity and privacy. Talk was given at University of Washington, brought by UWTV.

This is a relatively old video of cutting-edge research from University of Kentucky. Even though it mostly concentrates on video-processing aspects, privacy is the key topic, and some cryptographic techniques are used for various purposes.

A short presentation on lockpicking:

RSA Conference 2011 Keynote by Dr. Michio Kaku on next 20 years of technology. He is a great speaker, and the technologies are mind-blowing. You can probably imagine your role in this process.

A very nice and short video from RSA Conference 2011, related to the giants in the crypto world and the public-key breakthrough.
