Quantum Resistant Distributed Ledger Technology (or A Quantum resistant Distributed Ledger)

Lead Research Organisation: Brunel University
Department Name: Computer Science


1.The key/objective aims of the research.
The key objective of this research project is to develop a quantum resistant distributed ledger by making the current signature scheme resistant to quantum algorithms.
This research project will make the current signature scheme resistant to quantum algorithms by developing a novel signature scheme. The novel signature scheme will be based on a newly developed encryption system.
Further objectives:
Develop a new encryption system.
Test the security performance of the encryption system against already existing systems in use.
Implement the encryption system into distributed ledger technology.
2. What questions does the project intend to answer?
How susceptible are current distributed ledgers to quantum algorithms?
What are the practical and theoretical implications of quantum cyber-attack on distributed ledgers?
How does our novel encryption system compare to existing encryption systems.
What are the existing attacks on the digital signature used in distributed ledgers.
How was fast are quantum algorithms developing?
What is the long-term outlook on distributed ledgers?
3. The novel physical sciences/engineering methodology that will be carried out during the course of the project.
This research will give novel theoretically proof of our encryption system. Furthermore, the research will include practical implementation of the new encryption system, which will be quantitatively and theoretically analysed, in terms of security performance, against existing used cryptosystems. This analysis will include using standard classical cryptographic analysis, as well as using new and/or recently developed quantum algorithm simulators.
4. Add some potential applications or context describing the value of the research.
Using distributed ledgers many practical applications in industry and government. For example, distributed ledgers are vital in the use of cryptocurrencies (such as Bitcoin) and are currently being used in governments (such as the Estonian government which has experimented with a form of distributed ledger technology).
The practical implementation of this research project on distributed ledgers is that it will secure the digital signature used, as well as potentially using the new encryption system for other practical applications.
The key message of the practical implementation is that, the need for a quantum resistant distributed ledger is necessary for the continued long-term security and use of any distributed ledger technology, such as cryptocurrencies, manufacturing and government infrastructure.
