Extended Security Functionalities for Proof-of-Stake Wallets

-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(大理石2022)和(2)，以及作为与来自XX Network的David Chaum和Mario Yaksetig的联合工作，在第25届信息安全和密码学国际会议(ICICS 2022)上。此外，在第40届密码学与信息安全研讨会(SCIS 2023)上对这些结果进行了总结。虽然后来在应用密码学和网络安全国际会议(ACNS 2021)上提出的原始设计在安全保证方面得到了改进，但后者为结构引入了更好的能力。-可支出冷钱包新的热/冷钱包接口以及新的通信协议在国际安全和密码学会议(SECRYPT 2022)上展示。这项工作是莫纳什大学的拉斐尔·道斯利、巴西利亚大学的玛琳·法里亚斯、华盛顿大学的安德森·纳西门托和乔特·维尔迪以及马里奥·拉兰盖拉共同完成的。此外，这一扩展摘要还在第40届密码学与计算机安全研讨会(SCIS 2023)上发表。

- 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).
