Fault Analysis of Grain Family of Stream Ciphers
In this paper, we present fault attack on Grain family of stream ciphers, an eStream finalist. The earlier fault attacks on Grain work on LFSR whereas our target for fault induction is the NFSR. Our attack requires a small number of faults to be injected; 150 only for Grain v1 and only 312 and 384 for Grain-128 and Grain-128a, respectively. The number of faults are much lesser than the earlier ...
متن کاملPomaranch - Design and Analysis of a Family of Stream Ciphers ∗
Pomaranch is a synchronous, hardware-oriented stream cipher submitted to eSTREAM, the ECRYPT Stream Cipher Project. The cipher is designed as a cascade clock-controlled key-stream generator built on jump registers. This paper presents a discussion over the attacks on Pomaranch discovered so far. Particular focus is made on a new inherent property of jump registers that allows to construct their...
متن کاملCombined Side-Channel and Fault Analysis Attack on Protected Grain Family of Stream Ciphers
In this paper, we first demonstrate a new Differential Power Analysis (DPA) attack technique against the Grain family of stream ciphers (Grain v1 and Grain-128) by resynchronizing the cipher multiple times with the same value of the secret key and randomly generated different initialization vectors (IVs). Subsequently, we develop a combined side channel and fault analysis attack strategy target...
متن کاملA Differential Fault Attack on the Grain Family of Stream Ciphers
In this paper we study a differential fault attack against the Grain family of stream ciphers. The attack works due to certain properties of the Boolean functions and corresponding choices of the taps from the LFSR. The existing works, by Berzati et al. (2009) and Karmakar et al. (2011), are applicable only on Grain-128 exploiting certain properties of the combining Boolean function h. That ide...
متن کاملA Probabilistic Algebraic Attack on the Grain Family of Stream Ciphers
In 2005, Hell, Johansson and Meier submitted a stream cipher proposal named Grain v1 to the estream call for stream cipher proposals and it also became one estream finalists in the hardware category. The output function of Grain v1 connects its 160 bits internal state divided equally between an LFSR and an NFSR, using a non-linear filter function in a complex way. Over the last years many crypt...
