We show how to leverage the RKA (Related-Key Attack) security of blockciphers to provide RKA security for a suite of high-level primitives. This motivates a more general theoretical question, namely, when is it possible to transfer RKA security from a primitive P1 to a primitive P2? We provide both positive and negative answers. What emerges is a broad and high level picture of the way achievab...

I develop a novel method to detect election fraud from irregular patterns in the distribution of vote-shares. I build on awidely discussed observation that in some electionswhere fraud allegations abound, suspiciously manypolling stations return coarse vote-shares (e.g., 0.50, 0.60, 0.75) for the rulingparty,which seemshighly implausible in large electorates. Using analytical results and simula...

Purpose The purpose of this paper is to investigate the effect government-led programs on engagement individuals in entrepreneurship. Design/methodology/approach authors worked with 16 European countries between 2003 and 2014 were able benefit from 2008 natural experiment (i.e. global financial crisis) produce a robust investigation using regression kink design (RKD). Findings work shows that a...

sybil attacks pose a serious threat for wireless sensor networks (wsn) security. they can create problems in routing, voting schemes, decision making, distributed storage and sensor re-programming. in a sybil attack,the attacker masquerades as multiple sensor identities, that are actually controlled by one or a few existing attacker nodes. sybil identities are fabricated out of stolen keys, obt...

IgG4-related tubulointerstitial nephritis (IgG4-TIN) is the most common renal manifestation of IgG4-related kidney disease (IgG4-RKD) and may cause acute or chronic renal dysfunction. Imaging often shows heterogeneous densities in the kidneys, such as a mass or multiple nodules. Serology usually demonstrates high levels of serum IgG4 and total IgG. Most patients have other organs involvement by...

Standard Regression Discontinuity (RD) designs exploit a discontinuity (a jump) in the treatment probability to identify a local average treatment effect (LATE). RD identification fails or is weak when there is no jump or the jump is small. Unlike regression kink design (RKD), which requires a continuous treatment, this paper considers a binary treatment. This paper shows that without a jump, o...
