To enhance its resistibility to fault attacks,this paper proposed a non-concurrent fault detection scheme for controller circuit based on Finite State Machine(FSM).Using linear codes,this scheme was carried out by constructing one path to detect faults in the FSM.Finally,this paper used the scheme to design the security FSM circuit for NAF-based left-to-right scalar multiplication algorithm,and simulated and analyzed the circuit in resistibility to fault attacks.Through the simulation,and compared with the scheme of concurrent error detection,in the case of reducing frequently decoding workload of the state machine,this design can detect the error correctly and alarm,and it also improves the ability of fighting against fault attacks.
