Advanced Quantum-Secure Digital Signatures Technique Developed by Scientists
Research carried out by scientists at Monash University has led to the development of a method that vastly accelerates quantum-secure digital signatures, enhancing online transaction security and speed by as much as 20 times. This compelling research was published in a recent edition of the IEEE Transactions on Parallel and Distributed Systems.
The team at the forefront of this groundbreaking research is comprised of specialists who have been able to develop a streamlined method of using Falcon – a post-quantum digital signature algorithm – with graphic processing units (GPUs). Associate Professor Ron Steinfeld, a member of the team and expert in quantum-safe cryptography at Monash University’s Faculty of Information Technology, acknowledged the complexity of these quantum-safe signature algorithms like Falcon calling them intricate and time-intensive when it comes to GPU operations.
Falcon Transforming the World of Digital Security
The research zeroes in on optimizing the implementation of Falcon on GPUs. This innovative method paves the way for quantum-secure digital signatures that are 20 times faster in generating than the best contemporary CPU-generated signatures. Another author of the paper, Associate Professor Wai-Kong Lee, addressed the challenge of Falcon operationalization on GPUs, due largely to the signature scheme’s distinctive signing approach. The study endeavours to surmount this hurdle.
Across the globe, digital signatures play a pivotal role in facilitating and validating a wide spectrum of digital transactions. Dr. Raymond Zhao from CSIRO, another author of the study, commented on the heightening demand for more competent GPUs capable of managing intricate computational tasks.
Dr. Zhao cited the example of Chinese multinational conglomerate, Alibaba, which handles an average of 583,000 orders per second during peak periods. He noted that online payments usually employ digital signatures for enhanced security, underscoring the necessity of a swift, secure process for generating digital signatures in areas like e-commerce and Internet of Things (IoT) implementations.
Importantly, Falcon has received validation from the National Institute of Standards and Technology (NIST) in the United States, laying claim as one of the leading quantum-secure digital signature solutions. Dr. Zhao also made note of the global transition towards quantum-safe computer systems and the subsequent moves by governments to standardize computer networks in preparation for potential future quantum computer-based threats.
