The following article is adapted from a press release issued by the Laser Interferometer Gravitational-wave Observatory (LIGO) Laboratory, in collaboration with the LIGO Scientific Collaboration and V...
A new research project aims to unravel the physical limits of cell size in budding yeast, with the ultimate goal of learning more about how cells, the fundamental units of life, modulate size control ...
A study by Brown researchers finds that changes in tectonic plate thickness across the Denali Fault in Alaska impacts where it is located, shedding light on how major faults and earthquakes occur.
The liver’s ability to regenerate itself is legendary. Even if more than 70 percent of the organ is removed, the remaining tissue can regrow an entire new liver.
Scientists have developed two complementary bladder models to study urinary tract infections (UTIs) caused by E. coli: bladder organoids and a bladder-on-a- chip. The two studies reveal how bacteria i...
Physicists from across three continents report the first experimental evidence to explain the unusual electronic behavior behind the world’s thinnest superconductor, a material with myriad application...

The ability to synchronize behavioral, morphological and other transitions with the seasons is integral to the life cycle of most insects. A research team led by biologists at Tufts University has fou...
The ice worm is one of the largest organisms to spend its life in ice, and Washington State University scientist Scott Hotaling is one of the only people on the planet studying it.He is the author of ...
Securely managing encrypted data on an untrusted party is a challenging problem that has motivated the study of a variety of cryptographic primitives. A special class of such primitives allows an untr...
Secret-Sharing from Robust Conditional Disclosure of Secrets
cryptographic protocols secret sharing
2019/5/21
A secret-sharing scheme is a method by which a dealer, holding a secret string, distributes shares to parties such that only authorized subsets of parties can reconstruct the secret. The collection of...
A time-release protocol enables one to send secrets into a future release time. The main technical challenge lies in incorporating timing control into the protocol, especially in the absence of a cent...
Placing Conditional Disclosure of Secrets in the Communication Complexity Universe
information theoretic cryptography communication complexity
2018/12/3
In the Conditional Disclosure of Secrets (CDS) problem (Gertner et al., J. Comput. Syst. Sci., 2000) Alice and Bob, who hold nn-bit inputs xx and yy respectively, wish to release a common secret zz to...
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 ...
Recovering Secrets From Prefix-Dependent Leakage
Galton--Watson process discrete logarithm problem cryptanalysis
2018/9/6
We discuss how to recover a secret bitstring given partial information obtained during a computation over that string, assuming the computation is a deterministic algorithm processing the secret bits ...
