The government of China has formed a new national industrial consortium focused on the development and advancement of nuclear fusion technology, news outlets have reported.
Finnish utility Fortum and Westinghouse Electric Company of the USA have signed a memorandum of understanding to explore prerequisites for the development and deployment of new nuclear in Finland and ...
When deep learning models are deployed in the real world, perhaps to detect financial fraud from credit card activity or identify cancer in medical images, they are often able to outperform humans.
Scientists estimate that more than 95 percent of Earth’s oceans have never been observed, which means we have seen less of our planet’s ocean than we have the far side of the moon or the surface of Ma...
In a single day, enough sunlight strikes Earth to power the world for an entire year—that is, if we can find a way to capture that energy cheaply and efficiently. While the cost of solar energy has de...
New findings reveal how neurons build and maintain their capacity to communicate（图）

The nervous system works because neurons communicate across connections called synapses. They “talk” when calcium ions flow through channels into “active zones” that are loaded with vesicles carrying ...
Imagine a more sustainable future, where cellphones, smartwatches, and other wearable devices don’t have to be shelved or discarded for a newer model. Instead, they could be upgraded with the latest s...

How to leverage hardness of constant degree expanding polynomials over R to build iO
public-key cryptography Obfuscation
2019/9/16
In this work, we introduce and construct DD-restricted Functional Encryption (FE) for any constant D≥3D≥3, based only on the SXDH assumption over bilinear groups. This generalizes the notion of 33-res...
Pseudorandom functions are traditionally built upon block ciphers, but with the trend of permutation based cryptography, it is a natural question to investigate the design of pseudorandom functions fr...
How to leverage hardness of constant-degree expanding polynomials over $\mathbb{R}$ to build iO
FE Indistinguishability Obfuscation
2018/11/6
DD -restricted FE allows for useful evaluation of constant-degree polynomials, while only requiring the SXDH assumption over bilinear groups. As such, it is a powerful tool for leveraging hardness tha...
