,Donors’ Experience and Analysis, faulty ciphertexts. Finally, we combine all our observations and propose a countermeasure that employs randomness much more effectively to prevent state-of-the-art differential fault attacks against AES.

,Aid Recipients’ Experience and Analysis, choosing suitable round functions, we show that for odd ., differential 4-uniform S-boxes over . with the best known nonlinearity can be constructed via three-round Feistel structure. Some experiment results are also given which show that optimal 4-bit S-boxes can be constructed with 4 or 5 round u

Education Calling for Second Reform,ts of Fouque?et al. Such non-random faults induce, together with the infective countermeasure, more complex probability distributions than in the original proof; we analyze them using careful estimates of character sums over finite fields. The security proof is formally verified using appropriate ex
