Obfuscation for Evasive Functions

An evasive circuit family is a collection of circuits C such that for every input x, a random circuit from C outputs 0 on x with overwhelming probability. We provide a combination of definitional, constructive, and impossibility results regarding obfuscation for evasive functions: 1. The (average case variants of the) notions of virtual black box obfuscation (Barak et al, CRYPTO ’01) and virtua...

The Fighter Problem: Optimal Allocation of a Discrete Commodity

The Fighter problem with discrete ammunition is studied. An aircraft (fighter) equipped with n anti-aircraft missiles is intercepted by enemy airplanes, the appearance of which follows a homogeneous Poisson process with known intensity. If j of the n missiles are spent at an encounter they destroy an enemy plane with probability a(j), where a(0) = 0 and {a(j)} is a known, strictly increasing co...
