【Abstract】Blockchain systems often use public keys or addresses as pseudonym accounts to protect the identity of users. However, as the blockchain system is transparent, an adversary can analyze all the public keys or addresses and obtain some real information about users, making the pseudonym mechanism ineffective. CryptoNote V2.0 is the first blockchain sys-tem to introduce a one-time address technology to enable the true anonymity of a user. But it does not have rigorous security proof. Moreover, due to application requirements, for one thing, users need anonymity. For another, administrators need to trace the identity of anonymous users. Therefore, a traceable one-time address scheme for the interactive sys-tem of digital museum items is proposed to fulfill these concerns. It allows the recipient to receive transactions anonymously, and a supervisor can trace the identity of a user effi-ciently. Two security models are defined and two corresponding instances are constructed. We prove that our instances are secure in IND-PK-CPA/IND-PK-CCA mode, respectively. Analysis and experiments show that the proposed schemes are effective in tracing the long-term identity of a recipient. Finally, the challenges of user privacy protection are enhanced with the advancement of the integration of digital museum asset interactions with blockchain. We build a blockchain system for Digital Museum assets and implement our two scheme instances in it. The system can integrate museum heritage resources around the world, share data based on blockchain, provide a large number of interactions and collections, and achieve large-scale exhibitions.(c) 2023 Elsevier Inc.
