Provided are a device and a method for authentication, which can increase security during a security channel configuration between an electric vehicle (EV) and a charging station (CS) for PnC charging. A mutual authentication method according to an aspect of the present disclosure may be executed so as to allow an EV to perform PnC charging through communication with a CS device. The mutual authentication method comprises the steps of: accepting, from the CS device, 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 stored in a storage device of the EV, so as to authenticate an SECC; 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 through a handshake with the CS device; and transmitting or receiving an encrypted message to or from the CS device by using the symmetric key.
