Abstract: In Eurocrypt 2006, Bellare and Rogaway \cite{BeRo06} gave a proof of the PRP/PRF switching Lemma using their game-based proof technique. In the appendix of the same paper, they also gave an proof without games. In this paper, we give another proof of the switching lemma, which is simple and mathematically-clear and easy to uderstand. Our proof is based on \textit{the strong interpolation theorem}.
