New post on ! HD Wallet for Lattice Cryptography By: - illuzen 🔗 Highlights: - The proposed HD wallet uses lattice cryptography to enhance security against quantum attacks, focusing on the Dilithium signature scheme. - The research identifies two main challenges in adapting lattice cryptography for HD wallets: generating suitable private keys and the lack of operations for non-hardened keys. - The solution involves using HMAC output as a source for generating keys, ensuring compatibility with existing wallet standards like BIP32 and BIP44. - The implementation of the wallet is available as open-source, allowing for community testing and validation against established test vectors. - The study emphasizes the importance of securing digital signatures against quantum threats while maintaining the current hash functions. ELI5: This research introduces a new type of digital wallet that uses a special kind of math called lattice cryptography. It allows users to create many secure keys from a single backup phrase, making it easier to manage their digital assets, especially in a future where quantum computers could break traditional security methods.
