Quantum Cryptography Expert Talks About Blockchain Security in Startup Island Taiwan | Taiwan News – Gamingdeputy

TAIPEI (Taiwan News) — At its research center in Taipei, Taiwan, BTQ is preparing for a new era of cybersecurity by developing digital cryptography tools at the dawn of the era of quantum computing.

To most readers, this probably sounds very abstract, especially since the quantum computer has yet to be invented. However, governments and companies expect such a device to appear in the near future.

Excited by the opportunities and concerned about the potential dangers that quantum computers can pose, companies like BTQ and others are positioning themselves to provide solutions to protect digital assets from attacks using quantum computers.

Recently, BTQ CTO Cheng Chen-Mou (鄭振牟), along with host Jeremy Olivier, joined the Startup Island Taiwan podcast where he discussed some of the issues with post-quantum cryptography (PQC) and explained the work done by BTQ.

Post-quantum cryptography is a fascinating and complex field that combines the study of physics, mathematics, computer science and electrical engineering, said Cheng, who has been involved in the field as a developer and in academia for over 15 years.

To explain the relationship between quantum computing and post-quantum cryptography, Cheng said that for BTQ, quantum computing is often presented as an adversary. On the other hand, post-quantum cryptography is seen as the tools and skills necessary to defend against the risks posed by such an adversary.

Currently, one of BTQ’s main activities is blockchain cryptography, specifically the ongoing process of moving sensitive information across public networks to more secure blockchain networks. The National Institute of Standards and Technology (NIST) of the US Department of Commerce called for this transition.

Cheng also noted that NIST is playing an important role in facilitating this transition. Last July, after six years of research and analysis, NIST announced standardized algorithms for quantum computing operations. This announcement has been a boon for companies like BTQ as they can now start developing applications and related technologies using a set of globally accepted standards.

It is now an urgent priority for businesses and governments around the world to secure web transactions that still take place on unencrypted networks. Legacy networks are simply not immune to today’s cyber threats, Cheng said, and BTQ wants to ease this transition by exploring cryptographic tools to secure these new blockchain-based networks.

Using the metaphor of renovating a house, Cheng said that right now, the entire Internet needs to “replace all the pipes” to ensure strong online security and no weak links. Given the scale of such an operation, there are both opportunities and challenges on the horizon for those involved in PQC. Cheng says BTQ is just a small player, but he wants to be part of the effort.

Cheng noted that even devices with very little processing power, such as refrigerators or other home appliances, also need to be protected. One aspect of this process is the development of new hardware for such devices.

In September, BTQ announced a collaboration with the Taiwan Industrial Technology Research Institute (ITRI) to achieve this goal. They will work together to develop a new type of computer chip to increase the security of these new blockchain-based networks and hopefully reduce power consumption in the process.
