Once the IP addresses of terminals or servers are identified, they become vulnerable to cyber attacks from external sources, which can lead to serious damages such as service disruption. However, the information of source and destination IP addresses in IP packets cannot be concealed by encryption or other means since it is used for end-to-end transmission of data. To tackle this issue, the author proposed a method in previous research where the IP addresses of the destination and source are dynamically translated to proxy IP addresses at the boundary (edge) of the communication network. This makes it difficult to identify the actual IP addresses even if packets are intercepted at some point along the communication route. However, the implementation using existing software routers presents a challenge due to time-consuming updates of address conversion rules, resulting in significant communication delays, although the proposed method functions. This report discusses and evaluates the results of an investigation into an implementation capable of real-time address conversion without affecting communication.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","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":"2024-03-05","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"24","bibliographicVolumeNumber":"2024-IOT-64"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"created":"2025-01-19T01:34:15.534335+00:00","id":233044,"links":{}}
