- 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).
