Blockchain Resistant to Quantum Attack
Ľaš, Michal ; Perešíni, Martin (oponent) ; Malinka, Kamil (vedoucí práce)
The development of quantum computers presents new opportunities but also introduces a threat by compromising currently used cryptographic algorithms. This threat significantly impacts blockchain technology, which relies on various cryptographic principles. The objective of this work is to design and implement a blockchain that incorporates new post-quantum cryptographic algorithms resistant to attacks performed by quantum computers. The main part of my solution involves analyzing blockchain components vulnerable to quantum attacks, selecting appropriate post-quantum algorithms, and subsequently implementing them within the blockchain. The result of this work is an overview of blockchain vulnerabilities and their solutions in the post-quantum era. Additionally, the implemented solution compares the performance of multiple post-quantum and currently used algorithms. The results show that post-quantum cryptography can have a significant impact on blockchain performance. However, post-quantum blockchains will still be usable, and they will withstand the era of quantum computers.
