The problem with the SURF scheme

Thomas Debris-Alazard, Nicolas Sendrier, and Jean-Pierre Tillich

Abstract

There is a serious problem with one of the assumptions made in the security proof of the SURF scheme. This problem turns out to be easy in the regime of parameters needed for the SURF scheme to work. We give afterwards the old version of the paper for the reader's convenience.

Note: We found a serious problem in the security proof of the SURF scheme. We explain this problem here and give the old version of the paper afterwards.
