Sparsity is a naturally occurring characteristic in many real-world applications including signal denoising, outlier detection, and finance. On one hand, sparsity assumption allows people to tackle in...
Astronomers discover a rare “black widow” binary, with the shortest orbit yet（图）
“黑寡妇”双星 恒星 伴星环 银河系
2023/6/9
The flashing of a nearby star has drawn MIT astronomers to a new and mysterious system 3,000 light years from Earth. The stellar oddity appears to be a new “black widow binary” — a rapidly spinning ne...
Research done at Cornell has uncovered from gravitation wave data the first potential signs of spin-orbit resonances in binary black holes, a step toward understanding the mechanisms of supernovas and...

discrete logarithm index calculus elliptic curves
2019/3/22
Logical cryptanalysis, first introduced by Massacci in 2000, is a viable alternative to common algebraic cryptanalysis techniques over boolean fields. With XOR operations being at the core of many cry...
Solving binary MQ with Grover's algorithm
Grover's algorithm multivariate quadratics quantum resource estimates
2019/2/25
The problem of solving a system of quadratic equations in multiple variables---known as multivariate-quadratic or MQ problem---is the underlying hard problem of various cryptosystems. For efficiency r...
On the Hardness of Learning With Errors with Binary Secrets
complexity theory lattice based cryptography foundations
2018/11/5
We give a simple proof that the decisional Learning With Errors (LWE) problem with binary secrets (and an arbitrary polynomial number of samples) is at least as hard as the standard LWE problem (with ...
Secret Sharing with Binary Shares
