The problem with the SURF scheme
Thomas Debris-Alazard and 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.
