Pseudorandomness of Knapsacks over a Number Ring

Abstract

In this work, we study the pseudorandomness of the bounded Knapsack function family defined over a number ring ${R}$. We establish that if the Knapsack function family is one-way and certain related folded Knapsack function families are pseudorandom, then the original Knapsack is pseudorandom. This can be seen as a generalisation of the work of Micciancio and Mol presented at the CRYPTO-2011, for the case of Knapsack function families defined over arbitrary number ring.
