Disclosed is a method of detecting anomaly of an unmanned moving object by using a message ID sequence, and the method includes: collecting packet data generated in the unmanned moving object; pre-processing the collected packet data; and detecting an anomaly of the unmanned moving object based on a message ID pattern of the packet data by inputting the pre-processed packet data to a pre-trained neural network model.

The present disclosure relates to a two-phase Byzantine consensus method and system for state machine replication. A consensus method which is performed by a consensus system includes performing, by all of normal processes, consensus for a sequence number proposed by a process designated to be primary with respect to a client request according to an agreement protocol; and replacing the primary when the primary is suspicious of having a Byzantine fault according to a view change protocol.

A method for determining a reset cause of an embedded controller for a vehicle includes: executing an embedded controller for the vehicle by a central processing unit (CPU) of the embedded controller; generating a log based on information related to reset of the embedded controller collected from the running embedded controller, and a sequence number generated by the running embedded controller by the embedded controller; determining cause information of a reset trigger by analyzing the log including the reset trigger log, and determining reset cause information of the embedded controller based on the cause information of the reset trigger by a log analyzer of the embedded controller; storing a cause analysis result log including the reset cause information in a cause analysis result buffer in response to the reset cause information by the embedded controller; and storing the cause analysis result log in a non-volatile storage device.
