 note = {近年の5G環境の普及に伴い，通信の低遅延性と処理能力の両立を目的としたMEC (Multi-access Edge Computing)技術が注目を集めている．近藤ら[1]は，MECの実装にあたって強化学習を用い，リソース配分の効率化やフォールトトレランス性を実現している．しかし，ユーザの認証や処理代替の認可等，セキュリティ面には触れていない．そこで本研究では，先行研究の環境下での認証認可基盤：DIAMECを提案する．DIAMECは主にDiameterプロトコル・CHAP認証・チケットベースアクセス制御により構成されている．本研究では，DIAMECを仮想環境上に実装し，実働性とセキュリティ面の堅牢性を検証した．, In recent years, a technology called MEC (Multi-access Edge Computing) has been attracting attention in 5G networks. 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.},
