Sadly, Crypto 2 seems to be delayed to Oct 15 now.

My knowledge of this topic is limited but I believe if you are saying that the majority of crypto libraries have had major bugs, in the sense that they are made trivial to break, that you are overreaching. On the other hand if you are inclu

jerf started from two propositions, 1) "a sterotype exists" 2) "the study is correct" he argued that these propositions imply the proposition "a stereotype does not exist." This contradicts the starting propos

Yes algorithms courses are a bit of a grab bag. Really, whether you enjoy them just comes down to your interests. I loved learning algorithms because the important ideas can be conveyed without getting bogged down in applications. On top of

If you are really worried about government or government contractors building quantum computers in secret to break RSA in order to read your email you can just encrypt with either NTRU or McElice schemes which have been around for a while a

It bothers me that finding someone's location is such a problem since the technology exists to do it. How much would it cost to track a boat by GPS? Search and rescue missions over ocean must cost a fortune. Why don't governments

Average-case complexity is a not a topic I know a lot about, and I can't easily get the paper itself, but what the abstract seems to say is that for some particular NP complete problem, if an efficient average case algorithm exists for

Apparently it is very hard to prove results in average case complexity theory. We don't even know if computational problems that are hard on average assuming P!=NP exist, let alone actually designing a cryptosystem out of one.

There are two things wrong with this. First, you are assuming that a nonzero fraction of people will sign up for every open-membership community available to them, frequent, and vote in each such community. Realistically most people probabl

Let me be more specific. All that is required is "reasonable suspicion" in order to require access to all the files on your computer, unencrypted. "Reasonable suspicion" is a very weak requirement, as you can see from th

I've often heard the claim that elliptic curve cryptography is not used much in practice compared to RSA. I don't doubt its true but I would like to have some evidence for it so I can also say it without being a parrot. I don&#x27

It's either collecting call metadata on US citizens or open war mongering? I was going to say that you're giving a false choice but then I realized there doesn't really seem to be a connection between the choices you're giving.

I agree their front page is overloaded with silly human interest stories and other fluff. However, this is an update to an older story that was apparently broken on May 11th 2006 by USA today. It was covered by CNN tv on that day: http://m

I agree. I email my friends, or see them in person so I know what's going on in their lives. Too often people only want to analyze facebook as an organizational tool. But there is a great entertainment component built in as well. You get to

The study of solutions to equations only in the positive integers, or other subsets of integers also falls under Diophantine equations, as far as I know. Subset sum problems are obviously decidable since the number of values that must be tr

I don't have access to the original paper but from the summary here http://www.epi.umn.edu/cvdepi/study.asp?id=13 it looks like the study was only observational, roles were not randomly assigned.

I had a brief look at the paper. I got stuck on the section about scalability. I can't see how that could be implemented so that authentication can be done given that the nodes are untrusted (by which I mean implemented with a much smaller

If any evidence of the kind ever came out it would be the top story for every news organization in the US. So logically, since we all know with unshakable certainty that the NSA has such capabilities, they must be suppressing and controllin

The changes are good. On another note, don't buy into golden ratio hype. The supposed "beauty" of this ratio and its appearance "over and over again" in nature is one of those myths that just can't be killed. Every human should be made to r

Attempted proofs of Fermat's Last theorem by cranks used to be so common that Edmund Landau, a German mathematician, had a form letter for them: “Dear Sir/Madam: Your proof of Fermat’s Last Theorem has been received. The first mistake is on

The most dramatic example I know of someone who is older and also not a well known who found a major result is Kurt Heegner. He was a 59 year old private tutor and radio engineer with no previous published results when he proved the Class N

Real quantum computers don't exist. If one did exist it would need to factor numbers much larger than 4096 bits efficiently for it to be considered a real quantum computer.

There are 2 mostly distinct branches of number theory additive and multiplicative. Integer factorization is related to multiplicative number theory, but not really additive (as far as is known). This is a result in additive number theory so

I think linking to journal articles is a good thing even when they are paywalled like this but please give some context and a summary of the results.
