Problems solved by technology

From a business standpoint, authenticating EV users when charging EVs is important because eMobility service providers' revenues are at risk without proper means of authenticating EV users
Furthermore, the entire charging infrastructure and the grid that sits behind it are vulnerable to malicious attempts by unauthorized parties to exploit security gaps for political or financial motivation or gratification

Abstract

Disclosed is a cross-certificate method performed by an electric vehicle (EV) which desires to be 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 trusts a second V2G root certificate authority. The cross-certificate method according to an embodiment of the present invention may comprise the 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

technical field [0001] The present disclosure relates to a cross-certification method and apparatus, and more particularly, to a cross-certification method and apparatus for electric vehicle charging and a power transmission method using cross-certification. Background technique [0002] An electric vehicle (EV) is driven by an electric motor through electricity stored in a battery, and produces less pollution such as exhaust gas and noise, has fewer malfunctions, has a longer lifespan, and advantageously simplifies the Operation of EVs. [0003] Generally, EVs are classified into hybrid electric vehicles (HEV), plug-in hybrid electric vehicles (PHEV), and electric vehicles (EV) based on driving sources. HEVs use the engine as the main power source and the motor as the auxiliary power source. PHEVs have a main propulsion motor and an engine that is used when the battery is discharged. EVs have motors, but EVs don't have engines. [0004] An electric vehicle charging syst...
