项目摘要

- Extra Security Guarantees for ECDSA WalletsWe presented two works regarding extra security guarantees for wallets: (1) in the 3rd International Conference on Mathematical Research for Blockchain Economy (MARBLE 2022) and (2), and in the 25th Annual International Conference on Information Security and Cryptology (ICICS 2022) as a joint work with David Chaum and Mario Yaksetig both from XX Network. Furthermore, the summary of these results were presented at the 40th Symposium on Cryptography and Information Security (SCIS 2023). While the later improved in the security guarantees of the original construction from the original design presented at Applied Cryptography and Network Security International conference (ACNS 2021), the later introduces better capabilities for the construction.- Spendable Cold WalletThe novel Hot/Cold Wallet interface along with a novel communication protocol was presented at the International Conference on Security and Cryptography (SECRYPT 2022). This work was collaboration between Rafael Dowsley from the Monash University, Mylene Farias from University of Brasilia, and Anderson Nascimento and Jot Virdee, both from University of Washington, and Mario Larangeira. Furthermore, this an extended abstract was also presented at 40th Symposium of Cryptography and Computer Security (SCIS 2023).

- ECDSA钱包的额外安全保证我们提出了两项关于钱包额外安全保证的工作：（1）在第三届区块链经济数学研究国际会议（MARBLE 2022）和（2），以及在第25届信息安全和密码学国际年会（ICICS 2022）上，作为与XX Network的大卫Chaum和Mario Yaksetig的联合工作。此外，这些结果的总结在第40届密码学和信息安全研讨会（SCIS 2023）上发表。虽然后者在应用密码学和网络安全国际会议（ACNS 2021）上提出的原始设计中改进了原始构造的安全保证，但后者为构造引入了更好的功能。可使用的冷钱包在安全和密码学国际会议（SECRYPT 2022）上提出了新颖的热/冷钱包接口沿着以及新颖的通信协议。这项工作是拉斐尔Dowsley从莫纳什大学，Mylene Farias从巴西利亚大学，和安德森Nascimento和Jot Virdee，都从华盛顿大学，和马里奥Larangeira之间的合作。此外，这一扩展摘要也在第40届密码学和计算机安全研讨会（SCIS 2023）上发表。
