However, the security of these wallets primarily relies on users’ private keys, without enough care about the risks of the private keys’ theft and exposure. To address this issue, Chaum et al. (ACNS’21) introduced the concept of “Proof of Ownership”, allowing users to prove their ownership of private keys en when they are exposed publicly in a decentralized environment. Up to now, several related studies have been continuously proposed. However, these schemes require to interactively generate proofs, which are not suitable for specific scenarios. In addition, the computational complexity required by these schemes remains considerable. In this paper, we present an efficient approach that can “non-interactively” generate proofs for the ownership of secret keys. In particular, our approach utilizes zero-knowledge proof as well as hash function to allow users to present multiple proofs. Compared with start-of-the-art schemes, due to the non-interactive property and high efficiency, our approaches are applicable to a broader range of real-world environments.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1120","bibliographic_titles":[{"bibliographic_title":"コンピュータセキュリティシンポジウム2023論文集"}],"bibliographicPageStart":"1115","bibliographicIssueDates":{"bibliographicIssueDate":"2023-10-23","bibliographicIssueDateType":"Issued"}}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":228765,"updated":"2025-01-19T11:43:42.167149+00:00","links":{}}
