secret computation techniques and AES is one of the most popular block ciphers to encrypt data. When considering the combination of MPC and AES, it requires deep knowledge of AES’s S-box bit expansion and it becomes a high hurdle for implementation. On the other hand, when considering the combination of MPC and a cryptography technique, which consists of simple processes such as AND operation and cyclic shift, the hardle becomes very low and it is easy to be implemented to realize a practical application system. Moreover, there are lightweight ciphers and lightweight MACs with such characteristics. Using such lightweight cryptographic techniques is expected to help the system’s high performance. Moreover, as for MPC, communications between servers are required and it is inefficient to communicate between servers for each block process of the block cipher. We then propose a technique to combine several blocks when the communication is necessary. As an example of an application system, we implemented and evaluated a privacy protection system for pay TV services using MPC proposed by Ogawa et al. at HCI2019 by combining the lightweight cipher SIMON and the lightweight MAC LightMAC.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告セキュリティ心理学とトラスト（SPT）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2024-07-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"42","bibliographicVolumeNumber":"2024-SPT-56"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":237163,"created":"2025-01-19T01:39:38.310977+00:00"}
