Friday Squid Blogging: British Columbia "Squid Run" Is a Tourist Attraction

On James Island. As usual, you can also use this squid post to talk about the security stories in the news that I haven't covered. Read my blog posting guidelines here....

New Findings About Prime Number Distribution Almost Certainly Irrelevant to Cryptography

Lots of people are e-mailing me about this new result on the distribution of prime numbers. While interesting, it has nothing to do with cryptography. Cryptographers aren't interested in how to find prime numbers, or even in the distribution of prime numbers. Public-key cryptography algorithms like RSA get their security from the difficulty of factoring large composite numbers that are...

AES Resulted in a $250-Billion Economic Benefit

NIST has released a new study concluding that the AES encryption standard has resulted in a $250-billion worldwide economic benefit over the past 20 years. I have no idea how to even begin to assess the quality of the study and its conclusions -- it's all in the 150-page report, though -- but I do like the pretty block diagram...

Hello!  I just recently started a new blockchain technology meetup:  https://www.meetup.com/Government-Blockchain-Association-Hawaii/

Stanford has a new online open-to-the-public crypto class that looks really interesting!

Never mind. Further research reveals that what I just re-invented is essentially the Shamir Three-Pass Protocol originally developed in 1980.

I was looking into the classic XOR method of encrypting data for transfer and it occurred to me that there is actually a way to use that method but without the need to share the key between the sender and recipient. I wrote up a little program to verify the idea, and it does indeed work. Now, maybe this is already a tried and true approach, but I haven't come across anything about it on the Internet.

So, is there any member of the Crypto & Security group who would be willing to take a look at my approach and let me know whether or not it seems viable?

Interesting article on a new Google project: Google Native Client. Secure desktop apps but all over the web??

Brooke: Regarding writing the enigma machine in GWT, I wonder: are script tags allowed?
You can call in and out of Javascript from GWT using JSNI. We do this quite a bit on our current project.

Yo there, Dan:

Yeah, I do like the GWT, I would love to try out the 1.5 release. Regarding writing the enigma machine in GWT, I wonder: are <script> tags allowed? I would need to use that to load the entry point...

Hey Brooke - I love that the description of the group is encoded :-) I see from your ROT13 widget you are getting into Laszlo. Thats great!

Re: Writing the enigma machine's cipher in Javascript.

I just finished writing a wiki sytax -> html converter that runs on the client for ooi. I wrote it in Java and converted it to Javascript using GWT's compiler. You are limited to classes available in the JRE emulation environment, but it beats writing complex logic in Javascript (at least for me), and the compiler emits highly optimized code. You might want to try this approach.
