The current work analyses fault attacks on Trivium. These attacks exploit the slow pace of non-linearisation and reversibility of the encryption function. Cellular Automata can be effectively deployed to circumvent these shortcomings. CASTREAM, a CA based stream cipher, is difficult to reverse as well as highly non-linear and the non-linearity is attained very fast. In this paper, we show that CASTREAM is strong against fault attacks for which Trivium is vulnerable.
