We study the problem of identifying Finite Impulse Response (FIR) systems against random replay attacks with binary-valued observations in this paper. Replay attacks are modeled and the impact of attack strategies on the performance of parameter estimation algorithms is investigated. A defense algorithm that is consistent even during attacks is designed, and the problem of identifiability for the unknown parameters is discussed. Then, the asymptotic normality of this algorithm is given, and we derive the optimal defense strategy based on this. The proposed method’s rationality is verified by simulation example.
