In this research, we focus on virtual desktop infrastructure as a cloud application, and develop an authentication mechanism based on users' attributes using Cyphertext-Policy Attribute-Based Encryption. Using the mechanism the management of encryption keys is not complicated even if the number of users and attributes increase, and joint works are securely completed. We implement a prototype system of a virtual window us ing the authentication mechanism as the joint work on the virtual desktop and show the overhead of the authentication processing of the system. We show that the proposed mechanism is practical even if the overhead becomes larger if the number of attributes increase and those combination is more complicated. In addition, we show that our developed authentication mechanism is useful for screen sharing with multiple joint workers by comparison with the RSA cryptosystem.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"24","bibliographic_titles":[{"bibliographic_title":"インターネットと運用技術シンポジウム論文集"}],"bibliographicPageStart":"19","bibliographicIssueDates":{"bibliographicIssueDate":"2017-11-30","bibliographicIssueDateType":"Issued"},"bibliographicVolumeNumber":"2017"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-19T00:52:00.672634+00:00","id":184690,"links":{}}
