The adoption of Scalable service-Oriented MiddlewarE over IP (SOME/IP), a service-oriented architecture for in-vehicle networks, is being considered network was developed as a solution to these issues. However, SOME/IP lacks standard authentication and encryption mechanisms, exhibiting vulnerabilities to spoofing attacks. Previous studies have proposed methods such as mutual authentication using Message Authentication Code (MAC) and symmetric encryption. However, these approaches face cost challenges due to the need for authentication mechanisms on all devices. Conversely, centralized authentication methods using monitoring terminals have been proposed for CAN networks, but their implementation requires hardware modifications. In this study, we propose a centralized authentication system that verifies only server messages during SOME/IP service discovery. If a spoofing attempt is detected, the service is deactivated. This approach minimizes the impact on client devices and can be implemented with software modifications to servers and monitoring terminals. We implemented the proposed method using the vsomeip and confirmed its expected behavior in a practical environment.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告コンシューマ・デバイス&システム(CDS)"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2025-01-16","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"50","bibliographicVolumeNumber":"2025-CDS-42"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"updated":"2025-01-19T07:29:07.956116+00:00","created":"2025-01-19T01:46:53.854957+00:00","links":{},"id":241971}
