DeepSec 2023 Talk: Post-quantum digital signatures using Verkle tree and AI in post-quantum cryptography – Maksim Iavich

Sanna/ October 3, 2023/ Conference

Recent advancements in quantum computing research have made significant progress. If we achieve a functional quantum computer, it has the potential to undermine the security of current public key cryptosystems, which are widely integrated into commercial products. Although there have been proposed solutions to counter quantum attacks, these solutions currently grapple with security and efficiency concerns in everyday use. This talk focuses on exploring hash-based digital signature techniques, particularly those rooted in Merkle tree structures. The research deeply investigates the viability of Verkle trees and vector commitments, introducing pioneering concepts within this field. At DeepSec I will present a novel post-quantum digital signature, using modern technologies, such as Verkle tree. I will talk about the working methology of making the signature post-quantum secure. I will describe the attack on post-quantum digital signatures using machine

DeepSec 2022 Talk: Post-quantum Verkle Signature Scheme – Maksim Iavich

Sanna/ August 26, 2022/ Conference

We expect mass production of quantum computers in the near future. Quantum computers can easily break cryptographic schemes that are used in practice. Thus, classical encryption systems become vulnerable to attacks using quantum computers. There are research efforts to find encryption schemes that are resistant to attacks using quantum computers. Digital signatures are an important technology in securing the Internet and other IT infrastructures. A digital signature provides the authenticity, integrity, and identification of data. We use digital signatures in identification and authentication protocols. So, these secure digital signature algorithms are crucial in terms of IT security. Today, in practice, digital signature algorithms such as RSA, DSA, ECDSA are used. However, they are not quantum stable, as their safety relies on large composite integers, complex factorization and the computation of discrete logarithms. We asked
