Benefits of technology

The cross certification method in this patent allows for the flexible management of trusts in an EV charging network or system. This can help improve the reliability and security of the charging system.

Problems solved by technology

From a business point of view, it is important to authenticate the EV user when the EV is charged because revenue of the eMobility service provider will be at risk if there is no adequate manner of authenticating the EV user.
Further, the entire charging infrastructure and the power grid located behind the charging infrastructure are vulnerable to malicious attempts by an unauthorized group exploiting the security vulnerabilities for a political or financial motive or for a sense of fulfillment.

Abstract

A cross-certificate method is performed by an electric vehicle (EV) for being supplied with power from electric vehicle supply equipment (EVSE) associated with a charging point operator (CPO) having established a trust relationship with a first vehicle to grid (V2G) root certificate authority (rootCA) and a second V2G root certificate authority. The cross-certificate method may include steps of: requesting charging from the electric vehicle supply equipment; receiving, from the electric vehicle supply equipment, a certificate chain held by the electric vehicle supply equipment; and verifying whether or not a last certificate of the certificate chain has been signed by the second V2G root certificate authority, wherein the last certificate of the certificate chain can be a cross-certificate issued by the second V2G root certificate authority.

Description

BACKGROUND(a) Technical Field[0001]The present disclosure relates to a cross certification method and apparatus, more particularly, to the cross certification method and apparatus for use in an electric vehicle charging and a power transfer method using cross certification.(b) Description of the Related Art[0002]An electric vehicle (EV) is driven by an electric motor by power stored in a battery, and produces less pollution such as exhaust gas and noise compared with a conventional gasoline engine vehicle, fewer faults, a longer life span, and advantageously, operation of the EV is simplified.[0003]Typically EVs are classified into hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), and electric vehicles (EVs), based on a driving source. The HEV has an engine as a main power source and a motor as an auxiliary power source. The PHEV has a main power motor and an engine used when a battery is discharged. The EV has a motor, but the EV does not have an engine.[00...
