A mutual authentication method allows an electric vehicle (EV) to perform plug-and-charge (PnC) charging through communication with a charging station (CS) device. The mutual authentication method includes: accepting an SECC certificate chain including an SECC certificate and at least one charging device-based sub-certificate used for generation of the SECC certificate; verifying the SECC certificate by using the at least one charging device-based sub-certificate and a first root certificate; transmitting a verification result of the SECC certificate to the CS device, and providing the CS device with an EV certificate chain including an EV certificate for the EV and at least one EV-based sub-certificate used for generation of the EV certificate; accepting a verification result of the EV certificate from the CS device and generating a symmetric key; and transmitting or receiving an encrypted message to or from the CS device by using the symmetric key.
