Those who follow this link already know that I have been working with my co-authors from XX Networks, David Chaum and Mario Yaksetig to develop a special trick for wallets. The idea is that in a major, and catastrophic, event when several wallets are hacked, there is still a possibility of the rightful user issues a proof ownership of the wallet. This is the inspiration for our work with Sleeve presented at ACNS’21.
This time we developed a more formal security proof for our new construction, i.e., ‘Tweakable Sleeve’, which connects better to the state-of-the-art for ECDSA. Moreover, we changed the original construction by using Tweakable Hash Function instead of L-Tree data structure.
Our work was presented at MARBLE 2022
