A multi-charging apparatus includes a power converter, a first sensing unit configured to sense a power source introduced into the power converter from a motor or introduced into the motor from the power converter, and a controller configured to determine whether failure occurs in the first sensing unit, and execute a charging operation control for the power converter when a failure occurs.

An exhaust gas recirculation (EGR) control method includes a valve duty differentiated control including: detecting, by a controller, an engine operation region, a mixer region, and an external factor region as a valve control condition for an EGR valve duty correction variable for controlling an EGR system; applying, by the controller, the EGR valve duty correction variable to an EGR valve duty, which is set by a target air amount to an intake air amount, to calculate a minimum EGR valve duty; and outputting, by the controller, the calculated minimum EGR valve duty to an EGR valve as the EGR valve duty.

Disclosed are a system and a method for one-time password (OTP)-based authentication. The system for OTP-based authentication includes a transceiver module configured to receive an authentication request from a client and transmit a result of the authentication according to the authentication request to the client, an authentication accumulation management module configured to provide statistical information about authentication success of the client for each time interval within a predetermined effective range of time, an OTP generation module configured to generate a server-side OTP using previously stored authentication information and time information that is acquired from the statistical information about authentication success, and an authentication module configured to authenticate the client by comparing a client-side OTP included in the authentication request with the server-side OTP.
