If you think a promiscuous client is a scantily-dressed customer, you're in trouble. And I'm not talking about having an affair. Think an evil twin is a horror-movie villain? Wrong again. The horror you should be bracing yourself for is not on the silver screen — and it's not from a rolling pin flung at you from across the kitchen, for that matter. Rather, the trouble is in the airwaves and tar...

Mobile Evil Twin attacks stem from the missing authentication of open WiFi access points. Attackers can trick users into connecting to their malicious networks and thereby gain the capability to mount further attacks. Although some recognition and prevention techniques have been proposed, they have been impractical and thus have not seen any adoption. To quantify the scale of the threat of evil...

For a quartic primitive CM field K, we say that a rational prime p is evil if at least one of the abelian varieties with CM by K reduces modulo a prime ideal p|p to a product of supersingular elliptic curves with the product polarization. We call such primes evil primes for K. In [GL], we showed that for fixed K, such primes are bounded by a quantity related to the discriminant of the field K. ...

In both developing and developed countries, health ministries closely examine use of so-called nudges to promote population health and welfare. Cass Sunstein and Richard Thaler, who developed the concept, define a nudge as “any aspect of the choice architecture that alters people’s behavior in a predictable way without forbidding any options or significantly changing their economic incentives. ...
