indistinguishability

You start off with the indistinguishability stuff, which is not easy in itself. Toss in the distributed aspects of Internet applications and you've got yourself a proper mess.

CBC mode; I'm starting to come around to Colin's take on CTR because of ciphertext indistinguishability as I see more practical vulnerabilities that take advantage of it. I think the padding issue is a red herring.

There's a property in physics called indistinguishability. Electrons are an example of something that has this property.

You forgot to update the sentence about middle management, further strengthening my point about indistinguishability. Thanks for underlining that private sector isn't "much" better.

There happens to be a vast mathematical identity that the sum of the first n odd numbers is the n'th square number, allowing for that indistinguishability. But to claim that they're exactly the same realization of this function is obviously mistaken.

These days, I'm rather afraid that we've already reached that point - at least in the western world, most governments seem to have just become the corporations, infiltrated to the point of indistinguishability. I hope there's a way back, but I'm not particularly optimistic about it.

Astrophysicists do not separate such collapsars from actual black holes and call all them BHs due to practical reasons because of their actual indistinguishability."

This is not how indistinguishability works. The 'correct' to make this point would be to analyze the volume format, and reduce distinguishing the container to distinguishing the underlying block cipher from a pseudorandom permutation.

FTR, hcrypt predates indistinguishability obfuscation by a couple of years. As far as I can tell this really is a straightforward VM working with homomorphically-encrypted opcodes and data, and not an implementation of Garg and friends's work.

But I feel this entire argument is pushing for indistinguishability more than equality. There will never be indistinguishability between men and women.

How does deniable encryption improve over that, if in the end it comes down to indistinguishability?" I'm expecting them to realize that with a well-designed deniable system, they can't tell the difference between you being uncooperative and there being nothing incriminating to find."

>They adopt a different definition of obfuscation, called indistinguishability obfuscation. The criterion for success is that an adversary who is given obfuscated versions of two distinct but equivalent programsthey both compute the same functioncant tell which is which.

In that case indistinguishability becomes equivalent to saying nothing at all in scientific terms. The arguments in these kinds of articles have no choice but to become very tedious, mainly focusing on how people are getting ripped off, they cannot determine why homeopathic cures operate the same way as placebos--or not, which is the crux of the homeopathic argument.

I'm confused by this paragraph, and I wonder whether this indicates a limitation on my part, the part of whoever wrote the marketing copy, or the part of the developers of this platform: The problem of preventing an attacker associating a users encrypted ID to a decrypted ID is reducible to a security model called indistinguishability. We are using AES-CBC to perform this encryption, which means that our encryption scheme satisfies indistinguishability under a chosen plaintext attack, where the attacker is able to request encryptions, under the encryption key, of various plaintexts.
