- the access restriction process executed by the access restriction unit 12 will be explained using the flowchart shown in FIG. 4.
- the access control process is executed in common for all API-using applications.
- the access restriction unit 12 determines in S310 whether or not an API access request has been received from the target application 30 implemented in the external device. If the access restriction unit 12 determines that an API access request has been received, it transitions to S320, and if it determines that an API access request has not been received, it waits by repeating the same step.
- the access restriction unit 12 determines whether the destination API indicated in the API access request is an N-system API with no access restrictions, and if it is an N-system API, the process proceeds to S350, and if it is not an N-system API, the process proceeds to S330.
- the access restriction unit 12 determines whether an authenticator is attached to the API access request, and if an authenticator is attached, the process proceeds to S340, and if an authenticator is not attached, the process proceeds to S360.
- the access restriction unit 12 determines whether the authenticator attached to the API access request is compatible with the destination API, and if it is compatible, the process proceeds to S350, and if it is not compatible, the process proceeds to S360. Specifically, for example, if the destination API is an O-system API, the authenticator attached to the API access request may be determined to be compatible if it matches an O-system authenticator stored in the access management DB 13.
- the access restriction unit 12 determines that the target application 30 does not have access authority to the destination API, discards the API access request, and ends the process. At this time, the access restriction unit 12 may notify the source target application 30 that the API access request has been discarded.
- the in-vehicle system 100 uses the acceptance determination module 211 to determine whether the vehicle itself is in a state in which it can accept the target service. Then, as shown in FIG. 5, the in-vehicle system 100 transmits a result notification M1 indicating the result of the determination made by the acceptance determination module 211 to the target application 30 implemented in the external device.
- the target application 30 that receives the result notification M1 indicating that the service can be accepted sends an API access request M2 to the reliability confirmation module 212.
- Reliability information which is information related to the reliability of the service itself, is attached to the API access request M2.
- the access control unit 10 which has received the API access request M2, checks the destination API indicated in the API access request M2. In this case, since it is a request to access an N-system API (i.e., a positive judgment is made in S320), the access control unit 10 transfers the API access request M2 to the destination API.
- the destination API activates the trust confirmation module 212, which is a destination module, in accordance with the transferred API access request M2.
