Nothing Refreshes Like a RePSI: Reactive Private Set Intersection
private set intersection reactive functionalities
2018/4/17
Private Set Intersection (PSI) is a popular cryptographic primitive that allows two parties, a client and a server, to compute the intersection of their private sets, so that the client only receives ...
Lower Bounds on Obfuscation from All-or-Nothing Encryption Primitives
Obfuscation Witness Encryption Predicate Encryption
2017/6/9
Indistinguishability obfuscation (IO) enables many heretofore out-of-reach applications in cryptography. However, currently all known constructions of IO are based on multilinear maps which are poorly...
Some results on the existence of tt-all-or-nothing transforms over arbitrary alphabets
foundations combinatorial cryptography
2017/2/28
A (t,s,v)(t,s,v)-all-or-nothing transform is a bijective mapping defined on ss-tuples over an alphabet of size vv, which satisfies the condition that the values of any tt input co-ordinates are comple...

Much ado about nothing Astronomers empty space universe
2016/8/23
Researchers who are looking for new ways to probe the nature of gravity and dark energy in the universe have adopted a new strategy: looking at what’s not there.In a paper to appear in upcom...
Nothing is for Free: Security in Searching Shared & Encrypted Data
Multi-party Searchable Encryption (MPSE) Data Privacy Trapdoor Privacy
2016/1/9
Most existing symmetric searchable encryption schemes aim at allowing a user to outsource her encrypted data to a cloud server and delegate the latter to search on her behalf. These schemes do not qua...
(Nothing else) MATor(s): Monitoring the Anonymity of Tor's Path Selection
Tor Tor path selection Provable privacy
2016/1/8
In this paper we present MATOR: a framework for rigorously assessing the degree of anonymity in the
Tor network. The framework explicitly addresses how user anonymity is impacted by real-life charact...
We continue a study of unconditionally secure all-or-nothing transforms (AONT)
begun in [12]. An AONT is a bijective mapping that constructs s outputs from s
inputs. We consider the security of t in...
Pointing to Nothing? Empty Places Prime Infants’ Attention to Absent Objects
Absent Objects Empty Places
2015/12/18
People routinely point to empty space when referring to absent entities.
These points to “nothing” are meaningful because they direct attention to
places that stand in for specific entities. T...
All or Nothing? The Impact of School and Classroom Gender Composition on E

2015/9/24
We estimate the causal impact of school and classroom gender composition on achievement. We
take advantage of the random assignment of Korean middle school students to single-sex schools, coeducation...

There may be nothing peculiar to perceiving in a speech mode.
University of Cincinnati researchers have reached this threshold with a special structure that may someday lead to better ways of harnessing solar energy, stronger lasers or more sensitive medical dia...
Why there is something rather than nothing: The finite, infinite and eternal
infinite and eternal General Physics History and Philosophy of Physics
2012/5/31
Many believe that the deep question of "why is there something rather than nothing?" is unanswerable. The universe just is and no further explanation for its existence is possible. In this paper I exp...
Peak Nothing: Recent Trends in Mineral Resource Production

2011/8/11
Abstract: The production histories of seventeen raw materials are analyzed with the logistic model. Although many of these resources have exhibited logistic behavior in the past, they now show exponen...
Why "nothing" balances "something"

We propose a mechanism capable to provide a natural solution to two major cosmological problems, first cosmic acceleration and second the coincidence problem. Analyzing a specific brane-bulk energy ex...

When, in turn-of-the-20th-century America, Alfred L. Kroeber continued the work of Franz Boas, in establishing anthropology as an academic discipline in the US, he defined culture as a phenomenon sui ...
