  • Schnorr confirms paper is his, claims it “destroys RSA cryptosystem” | Hacker News

    Schnorr converts the integer factorization problem to lattice problems: SVP and CVP. Then he claims he had an efficient algorithm to solve this particular instance of SVP and CVP, thus RSA is destroyed. But, the hardness assumption of SVP and CVP in general is the very foundation that another branch of public-key cryptosystems - lattice-based cryptography - is built upon.

  • Apophis Passes the Earth on Friday

    Scientists will be watching the 370 meter-wide asteroid 99942 Apophis fly by the Earth this Friday, albeit from a safe 0.11 AU away. On Friday the 13th, April 2029, however, Apophis will pass within 31,000 km of the Earth’s surface, inside the orbit of geostationary satellites. Fortunately, while originally estimated at a 1-in-37 chance of a collision in 2029, that possibility has since been ruled out.

  • Molybdenum disulfide ushers in era of post-silicon photonics

    Researchers have measured giant optical anisotropy in layered molybdenum disulfide crystals for the first time. The scientists suggest that such transition metal dichalcogenide crystals will replace silicon in photonics. Birefringence with a giant difference in refractive indices, characteristic of these substances, will make it possible to develop faster yet tiny optical devices.

    "Whereas previously we were limited to changes in geometry and effective refractive index to create new optical circuits and devices, giant anisotropy provides an additional degree of freedom to manipulate light," says Volkov. - "Unexpectedly, we found out that naturally anisotropic materials enable us to build compact waveguides literally on the edge of the diffraction limit. It gives us an opportunity to compete with silicon photonics. Now we can safely not only talk about post-silicon photonics but also implement it."
