Gosh Sammy, so the "gap between indistinguishability obfuscation
and efficient functional encryption is narrowing! Whoopee! Sam does this
word salad of nonsense mean anything to you? I'm sure it does not. If
you had ANY idea what they are talking about you could discuss it as
requried by the charter of the group. We know that is NEVER going to
happen, And you a math major too! Tsk tsk.

Are you qualified and prepared to discuss it? And why ask Sam? He provided a link to the source for the subject. Wouldn't you prefer to discuss it with the authors rather than second hand? As far as I know, I am the only person who knows what gravity IS. Would you like to discuss what gravity is? Tell me what you know about it and I can start by telling you that you are 95% wrong. Furthermore, how do intend to discuss it when you are so ignorant of it? Maybe you can list the subjects that YOU are proficient in and we can make this group focus on that. Hmm. Let's see now. How to use discussion space with computer artwork? How about a complaint and rudeness seminar? I guess not. That is not in the charter, is it? Well. Gravity it is then. You start.

So far, candidate IO constructions were based on specific assumptions on algebraic objects called multi-linear graded encodings. We present a generic construction of indistinguishability obfuscation from public-key functional encryption with succinct ciphertexts and sub-exponential security. This shows the equivalence of indistinguishability obfuscation and public-key functional encryption, a primitive that has so far seemed to be much weaker, lacking the power and the staggering range of applications of indistinguishability obfuscation. As an application, we obtain a new candidate IO construction based on the functional encryption scheme of Garg, Gentry, Halevi, and Zhandry [Eprint 14] under their assumptions on multi-linear graded encodings. We also show that, under the Learning with Errors assumptions, our techniques imply that any indistinguishability obfuscator can be converted to one where obfuscated circuits are of linear size in the size of the original circuit plus a polynomial overhead in its depth. Our reduction highlights the importance of ciphertext succinctness in functional encryption schemes, which we hope will serve as a pathway to new IO constructions based on solid cryptographic foundations.

None. Nada. Zip. Physicists use randomness for things like Monte Carlo simulations. In such cases any source of randomness is sufficient.

Go ahead. Introduce a physics subject that YOU are qualified to talk about. Just remember though. You will be discussing it with the all spamming shitheads you complain about.

It's called the Monte Carlo methodology and it shifts a thoroughly inappropriate topic into one that is highly suitable for physics. I think, you idiotic turd-brain, that you may have completely missed the point.

I don't have a degree in randomness. There is no true randomness but we can be philosophical about it. Let's start with my favorite thought. If there is no end, why should there have been a beginning? Link that to entropy and we find that entropy can only exist in closed systems. Overall there is still an order but the order changes with time. Nothing (no thing) ceases to exist except in form. This change is not random but is rather an order in itself. Creation and annihilation do not exist. Compare to the thought of an eternal god. In the so-called entropy that we are aware of, we are also aware that degenentropy can take place. In an ideally closed system we realize that restrictions apply such that a given energy/matter total will not change. And although the combinations seem limitless, if we hold to a discreteness of things, only a certain set of combinations and permutation apply within that space. That said, we are becoming aware that matter is only energy in a lumpy form. That lumpy form is the result of discrete laws due to the properties of energy. Once you have discrete laws, it places limits on activity to form in a timely way. In an unbounded space, almost by definition, an apparent randomness can occur. But because there are laws governing behavior, a true randomness cannot occur. An apparent example of this is gravity but that in itself requires an internal pressure and lumpy energy. Otoh, even though space can be limitless, until energy reaches a limit in an empty space, it will have an internal pressure. So even if there were a true randomness, we would still have no means to use it.
