ALMA volcanic impact atmosphere Jupiter moon Io
2020/11/6
New radio images from the U.S. National Science Foundation-funded Atacama Large Millimeter/submillimeter Array, ALMA, show for the first time the direct effect of volcanic activity on the at...
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...
ProtectIOn: Root-of-Trust for IO in Compromised Platforms
Compromised Platforms control systems
2019/7/31
Security and safety-critical remote applications such as e-voting, online banking, industrial control systems, medical devices, and home automation systems rely upon user interaction that is typically...

Output Compression, MPC, and iO for Turing Machines
Randomized encodings compact MPC indistinguishability obfuscation
2018/11/13
In this work, we study the fascinating notion of output-compressing randomized encodings for Turing Machines, in a shared randomness model. In this model, the encoder and decoder have access to a shar...
FE and iO for Turing Machines from Minimal Assumptions
indistinguishability obfuscation functional encryption Turing machines
2018/11/9
We construct Indistinguishability Obfuscation (iO) and Functional Encryption (FE) schemes in the Turing machine model from the minimal assumption of compact FE for circuits (CktFE). Our constructions ...
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...
We give a simple construction of indistinguishability obfuscation for Turing machines where the time to obfuscate grows only with the description size of the machine and otherwise, independent of the ...
Indistinguishability Obfuscation Without Multilinear Maps: iO from LWE, Bilinear Maps, and Weak Pseudorandomness
Indistinguishability Obfuscation Functional Encryption
2018/6/25
The existence of secure indistinguishability obfuscators (iO) has far-reaching implications, significantly expanding the scope of problems amenable to cryptographic study. All known approaches to cons...
The Usefulness of Sparsifiable Inputs: How to Avoid Subexponential iO
indistinguishability obfuscation extremely lossy functions subexponential assumptions
2018/5/23
We consider the problem of removing subexponential assumptions from cryptographic constructions based on indistinguishability obfuscation (iO). Specifically, we show how to apply complexity absorption...
Non-Trivial Witness Encryption and Null-iO from Standard Assumptions
witness encryption non-trivial efficiency null-iO
2017/9/14
A witness encryption (WE) scheme can take any NP statement as a public-key and use it to encrypt a message. If the statement is true then it is possible to decrypt the message given a corresponding wi...
Taking advantage of a rare orbital alignment between two of Jupiter’s moons, Io and Europa, researchers have obtained an exceptionally detailed map of the largest lava lake on Io, the most volcanicall...
IO-DSSE: Scaling Dynamic Searchable Encryption to Millions of Indexes By Improving Locality
secret-key cryptography searchable encryption
2016/12/10
Free cloud-based services are powerful candidates for deploying ubiquitous encryption for messaging. In the case of email and increasingly chat, users expect the ability to store and search their mess...
