WebSep 10, 2007 · This paper describes a DFA (differential fault analysis) mechanism on the AES key scheduling process and shows how an entire 128-bit AES key can be retrieved. … Web(AES) [1]. Subsequently, many DFA were proposed on AES cryptosystem [6,11, 14,15,17] with the aim to reduced the number of faulty ciphertext required by the attack. However the DFA on AES can be divided into two categories. One in which the fault is induced in AES states, another in which the fault is induced in the key schedule.

Differential fault analysis of AES: Toward reducing number of faults

WebSep 8, 2008 · In this paper we show a new differential fault analysis (DFA) on the AES-128 key scheduling process. We can obtain 96 bits of the key with 2 pairs of correct and faulty ciphertexts enabling an easy exhaustive key search of 2 32 keys. Furthermore we can retrieve the entire 128 bits with 4 pairs.

DFA byte attack on AES-192 includes inducing fault and obtain round keys, which on further mathematical analysis would give us AES-192 key. The primary step involves inducing fault in the key-11 just before scheduling key-12.
