Abstract

In this paper we propose Differential Fault Attack (DFA) on two Fully Homomorphic Encryption (FHE) friendly stream ciphers Rasta and $\text {FiLIP} _ {\text {DSM}} $. Design criteria of Rasta rely on affine layers and nonlinear layers, whereas $\text {FiLIP} _ {\text {DSM}} $ relies on permutations and a nonlinear fil- ter function. Here we show that the secret key of these two ciphers can be recovered by injecting only 1 bit fault in the initial state. Our DFA on full round (# rounds = 6) Rasta with 219 block size requires only one block (i.e., 219 bits) of normal and faulty keystream bits. In the case of our DFA on FiLIP-430 (one instance of $\text {FiLIP} _ {\text {DSM}} $), we need 30000 normal and faulty keystream bits.
