Hash-based refers to cryptographic schemes that derive their security properties from the characteristics of cryptographic hash functions. These functions convert arbitrary-length data into fixed-length outputs, providing data integrity and authentication. They are fundamental building blocks in digital security.
Context
In blockchain technology, hash-based structures are indispensable for securing transaction data, linking blocks in an immutable chain, and verifying digital signatures. Current research in post-quantum cryptography includes hash-based signatures, which are considered resistant to quantum computer attacks. This development is crucial for ensuring the long-term security of digital assets against future computational advancements.
This review synthesizes post-quantum cryptography to fortify blockchain security against future quantum attacks, ensuring enduring trust in decentralized systems.
