Modeling and Analysis of AES Differential Fault Attack
Nie Qin-wu · Jisuanji gongcheng · 2010
This paper examines the ability of Advanced Encryption Standard(AES) against the differential fault attack.It uses the byte-oriented fault model against AES key schedule,and compares the differences between correct and faulty secret information embedded in a system to retrieve seed key.Theoretically,the 128 bit master key for AES can be obtained by using 104 faulty ciphertexts and retrieving 2 bytes of tenth round keys by exhaustive search.For the fact that the byte position where the fault happens is not equally distributed,there is little differences between the theoretical value and the number of faulty ciphertexts needed in the attack experiment result.
