Expander Graphs are Non-Malleable Codes
Non-malleable code Split-state Explicit Constructions
2018/11/8
Any dd-regular graph on nn vertices with spectral expansion λλ satisfying n=Ω(d3log(d)/λ)n=Ω(d3log(d)/λ) yields a O(λ3/2d)O(λ3/2d)-non-malleable code in the split-state model.
Must the Communication Graph of MPC Protocols be an Expander?
secure multiparty computation expander graph communication locality
2018/6/5
Secure multiparty computation (MPC) on incomplete communication networks has been studied within two primary models: (1) Where a partial network is fixed a priori, and thus corruptions can occur depen...
Fast Pseudorandom Functions Based on Expander Graphs

2016/12/10
Our proofs are based on a new search-to-decision reduction for expander-based functions. This extends a previous reduction of the first author (STOC 2012) which was applicable for the special case of ...
Efficient Robust Secret Sharing from Expander Graphs
Robust Secret Sharing Expander Graphs Secure Message Transmission
2016/7/29
Threshold secret sharing is a protocol that allows a dealer to share a secret among nn players so that any coalition of tt players learns nothing about the secret, but any t+1t+1 players can reconstru...
Near-linear time, Leakage-resilient Key Evolution Schemes from Expander Graphs
secret-key cryptography
2014/3/5
We develop new schemes for deterministically updating a stored cryptographic key that provide security against an internal adversary who can control the update computation and leak bounded amounts of ...

A growth and digestibility study was conducted using Osmanabadi goat male kids by feeding complete diets in the form of mash or expander extruded pellets containing different levels of red gram (Cajan...
Expander Graph Based Overlapped Chunked Codes
Expander Graph Based Overlapped Chunked Codes
2012/12/4
Chunked codes are a variation of random linear network codes with low computational complexities. In chunked codes, the packets in a file are grouped into small (non-overlapped or overlapped) chunks, ...
Design and Analyses of a Planar Zoom Module as a Beam Expander

2011/11/25
A novel planar zoom module (PZM) is presented in this article. The PZM is realized by integrating optical elements on its surfaces with the folding optical axis and performing the zoom function by tra...
On the Role of Expander Graphs in Key Predistribution Schemes for Wireless Sensor Networks
cryptographic protocols / Wireless sensor networks key management key predistribution expander graphs
2012/3/23
Providing security for a wireless sensor network composed of small sensor nodes with limited battery power and memory can be a non-trivial task. A variety of key predistribution schemes have been prop...

2010/10/19
We investigate deterministic design matrices for the fundamental problems of error prediction and model selection. Our deterministic design matrices are constructed from unbalanced expander graphs, a...
Using the construction of a nonorientable Curtis-Tits group of type A˜n, we obtain new explicit families of expander graphs of valency five for unitary groups over finite fields.
Nonsurgical Rapid Maxillary Expansion in Adults: Report on 47 Cases Using the Haas Expander
Maxillary expansion Surgically assisted maxillary expansion Haas expander Posterior crossbite Transverse dimension Adult treatment Mandibular rotation Gingival recession
2008/12/29
Rapid maxillary expansion (RME) in the adult is thought to be an unreliable procedure with several adverse side effects and, consequently, surgically assisted RME is considered the preferred proce...
