Abstract

We have reproduced our disputed simulation results from our original article as well as the simulations of the discussion article of Krack and Gross referenced above in the title. We have found several inaccuracies and omissions in the discussion article that invalidate its authors’ main claims. We also briefly address inherent performance differences between the SSMTool and the NLvib algorithms to the benefit of the former.
