Fault Analysis of Stream Cipherssearch literature contains many examples of fault attacks on public key cryptosystems and block ciphers, but surprisingly we could not find any systematic study of the applicability of fault attacks to stream ciphers. Our goal in this paper is to develop general techniques which can be used to attac

A Differential Fault Attack Against Early Rounds of (Triple-)DESunds of the cipher to extract the secret key. In this paper we describe a DFA attack that exploits computational errors in early rounds of a Feistel cipher. The principle of the attack is to force collisions by inducing faults in intermediate results of the cipher. We put this attack into practice a

Findings: Interpersonal Analysis,In this paper we show how the usage of Residue Number Systems (RNS) can easily be turned into a natural defense against many side-channel attacks (SCA). We introduce a Leak Resistant Arithmetic (LRA), and present its capacities to defeat timing, power (SPA, DPA) and electromagnetic (EMA) attacks.
