THIS PAPER IS: a nice, thought-provoking paper that is nevertheless purely speculative , and also more than a little tongue-in-cheek in parts. (Note that one of the keywords is "Make RSA Great Again".) It's basically pointin

It absolutely is - one of the keywords is "Make RSA Great Again", ffs.

From the abstract: "The new time complexity is asymptotically worse than Shor’s algorithm, but the qubit requirements are asymptotically better, so it may be possible to physically implement it sooner." This is a nice result that

I'm not an OS person, so forgive me if this is a stupid question: Lots of people are excited about Intel SGX and similar things. Are there any interesting ways people are thinking about combining, like, Docker containers with SGX encla

I second this - Gross is a phenomenal lecturer. These videos would probably be a great supplement to any self-study of algebra.

Most of the modern theory of error-correcting codes has its roots in abstract algebra. It's also important in theory - Babai's recent celebrated quasipolynomial algorithm for graph isomorphism relies on group theory. Most of the r

Cool article! Gray codes are used in cryptography sometimes too; the most well-known example is probably the Offset Codebook (OCB) authenticated encryption scheme, which uses a Gray code to compute tweaks: http://web.cs.ucdavis.e

The prof of my applied ML class this semester jokingly refers to ML research's approach to statistics as "punk stats", which I find to be pretty accurate.

Of course not; I never said it did matter. Hypothetically, if Google never happened and I was a lead dev looking across the table at Sergey Brin deciding whether to hire him with that resume, I'm saying I absolutely would. Any hiring m

Contra all the chuckleheads making jokes about him never getting hired anywhere today, this is actually an extremely impressive resume for a third-year graduate student. He had a sole-author publication in a top conference already!

If this jury-rigged, duct-taped "password hashing" scheme impresses you, I've got some land in Florida you might be interested in. Seriously, though, it's a complete fallacy to think that more complicated password hashin

You include things like DSA and ECDSA, which are not hash algorithms, but signatures. Is a signature being computed internally? If so, with what key?
48.
by swordswinger12 10y ago
Maybe nothing, but it's just kind of a weird, nonstandard way of doing things. Also it's not immediately obvious to me that your method meets modern security definitions like IND-CCA2.

So is there a per-chunk MAC, or do you rely on the signed hashes of ciphertext for the integrity and authenticity of each chunk?
50.
by swordswinger12 10y ago
Can you describe your file encryption procedure? In the Meta::Chunk class the 'encrypt' function only computes AES-CBC with no MAC, but there are calls to compute_strong_hash at other points in the library. There are references to

Have you thought about just not using the phrase "zero knowledge" at all?

-Usually the SSE model accounts for a malicious server that just stores every search token it's given, so the server doesn't need to reconstruct them. - You could store W on the server, but you would leak additional information to

I haven't looked closely at the full construction, but it's fairly similar to an earlier paper by Cash et al. ( https://eprint.iacr.org/2014/853 ) which is surprisingly practical - their system can do keyword s

Oh god, I still have nightmares about Herstein. I took an undergrad algebra class from a very old-school prof who thought it would be good for undergrads to be exposed to some of the problems - they gave all of us quite a bit of trouble.

Why no Halmos, "Finite-dimensional vector spaces"? It's pretty theoretical but very approachable also.

Actually the secure comparison protocol is the easy part - even generic SMC techniques are getting really fast these days. Also, they only involve about as much heavyweight crypto as a few TLS handshakes. Extracting a per-user fuzzy fingerp

This sentence worries me: "any secure computation algorithm that can compare our choice of user behavioral signature without exposing it" because it makes it seem as though there are lots of these just lying around. It seems like

This is a garbage, clickbait, content-free article that purposely misquotes the Riffle paper.
