MEC realizes processing near mobile equipments and achieves both low latency and processing capabilities. In the previous study on MEC implementation, Kondo et al.[1] proposed a mechanism using reinforcement learning. It optimizes the allocation efficiency of server resources and realizes its fault tolerance. However, it doesn't mention the security aspect, including user authentication and authorization in process substitution. In this study, we propose an authentication and authorization mechanism in MEC called DIAMEC. The core elements of DIAMEC are Diameter protocol, CHAP authentication, and ticket-based access control. We confirmed the availability and the robustness through the Proof-of-Concept implementation on a virtual 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":"研究報告インターネットと運用技術（IOT）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2025-07-21","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicVolumeNumber":"2025-IOT-70"}]},"relation_version_is_last":true,"weko_creator_id":"80578"},"id":2003105}
