Random thoughts about random things…by Jonathan Katz. May 19, 2014. In preparing the second edition, we have made a concerted effort to. A more practical perspective. While retaining a rigorous approach. This is reflected in a number of changes and additions we have made:. We have increased our coverage of. Introducing them as variant of pseudorandom generators, discussing stream-cipher modes of operation, and describing modern stream-cipher design principles and examples. After much consideration, we ha...

Random thoughts about random things…by Jonathan Katz. April 24, 2015. Upcoming CyberFETCH Spotlight Interview. Since I haven’t been writing much content on my blog, I may as well use it to advertise other things I’m doing. I’m going to be doing a version of “ask me anything” on the CyberFETCH.org website. (See announcement below.) The first question you can ask me is “why don’t you blog more often…? 8212;——————————————. So please, check out the link below.

Real-World Crypto, Day 2, Session 1 | Random bits
https://jonkatz.wordpress.com/2014/01/14/real-world-crypto-session-i
Random thoughts about random things…by Jonathan Katz. January 14, 2014. Real-World Crypto, Day 2, Session 1. The workshop kicked off with two talks on OPACITY. OPACITY is a protocol suite with two protocols: ZKM and FS. Both of these are Diffie-Hellman-based authenticated key-agreement protocols, geared toward smartcards, that incorporate some privacy measures. It was developed by the company ActiveIdentity, is apparently supported by the US Department of Defense, and has been standardized. He concluded ...

Random thoughts about random things…by Jonathan Katz. January 14, 2014. Real-World Crypto, Day 2, Session 3. I now see the problem with live-blogging: once you start, you are not allowed to stop…). Currently, the drive uses CBC/XTS mode for encryption, which means the encrypted data can potentially be modified in predictable ways. Addressing this seems like an interesting research direction related to the 2nd session. The new cipher, called PRINCE. The final talk, by Francois Dupressoir, was extremely in...

My course goes live! | Random bits

Random thoughts about random things…by Jonathan Katz. November 10, 2014. My course goes live! With excitement mixed with trepidation I watched my MOOC. On cryptography go live today! It is a mixed blessing to have 35,000 students taking the course, and already posting comments (and pointing out errors). It was a huge investment of time to get to this point, but so far students seem to be finding it worthwhile. Wait until we get to defining computational security. =). Laquo; Getting closer….

Random thoughts about random things…by Jonathan Katz. January 14, 2014. Real-World Crypto, Day 2, Session 2. The second session was on encryption. Jonathan Trostle kicked things off with a talk about authenticated encryption. Besides the “standard” security goals, he mentioned the idea of. One point he made, which is obvious but nevertheless bears repeating (especially in light of the CAESAR competition. Tom Shrimpton spoke next about format-transforming encryption. (I had heard a previous talk on th...

Random thoughts about random things…by Jonathan Katz. February 1, 2013. Undergraduate Research Opportunities this Summer. I will be involved in two NSF REUs (“Research Experience for Undergraduates”) this coming summer. One, whose webpage. Is already live, focuses on cybersecurity; the other. Focuses broadly on crypto, algorithms, and discrete math. If you know of any bright undergrads (or if you happen to be an undergrad reading this! Feel free to contact me. November 2, 2012.
