The security of all RSA and discrete log bits
Johan Håstad,Mats Näslund +1 more
TL;DR: In this paper, the security of individual bits in an RSA encrypted message EN(x) was studied, and it was shown that predicting any single bit in EN (x) with only a nonnegligible advantage over the trivial guessing strategy, is (through a polynomial-time reduction) as hard as breaking RSA.

On the List-Decodability of Random Linear Codes
TL;DR: In this paper, it was shown that a list size of O(1/ ϵ) is sufficient to have rate within ϵ of the capacity of a fixed finite field.
Proceedings ArticleDOI
On the advantage over a random assignment
Johan Håstad,S. Venkatesh +1 more
TL;DR: This measure compares the performance of an approximation algorithm to the random assignment algorithm, and is focused on for the optimization problems, Max-Lin-2, in which the authors need to maximize the number of satisfied linear equations in a system of linear equations modulo 2.
Proceedings ArticleDOI
Funkspiel schemes: an alternative to conventional tamper resistance
TL;DR: This work investigates a simple method of fraud management for secure devices that may serve as an alternative or complement to conventional hardware-based tamper resistance, and denotes this idea by the German term funkspiel, meaning “radio game.”
Proceedings ArticleDOI
Randomly supported independence and resistance
Per Austrin,Johan Håstad +1 more
TL;DR: It is proved that for any positive integer k, there is a constant ck such that a randomly selected set of c(sub)k n n Boolean vectors with high probability supports a balanced k-wise independent distribution.
