Monash experts: Australia’s quantum investment: Will our cybersecurity infrastructure cope?

Monash University 2 mins read

Monash University experts are available to comment on the Australian government’s almost $1 billion investment to build the world’s first commercially useful quantum computer and cybersecurity measures that are needed to support this quantum leap.

“As the reality of large-scale quantum computers draws closer, Australia must also pay attention to the impact of quantum computing on cybersecurity. It is well known in the research community that powerful quantum computers can render today’s classical encryption and cybersecurity mechanisms useless. These mechanisms are embedded in every part of our digitalised world from social media to securing critical infrastructure. 


“We must prepare for the post-quantum world by also investing in research on quantum-safe technologies including post-quantum cryptography. This preparation should also include training the next generation of experts in quantum-safe technologies. 


“Cybercriminals and other powerful adversaries can store encrypted sensitive information today in the hope to recover the information later using a quantum computer. We call this a ‘harvest now, decrypt later’ attack. As a result, today’s sensitive information unprotected against quantum computers may be exploitable in the future.


“It is important to secure our communications and the internet today, well ahead of what researchers informally call ‘Q-Day’, a near future where large-scale quantum computers would become available.”

  • Blockchain security

The following can be attributed to Associate Professor Steinfeld:

“The research community has developed quantum-safe cryptography technologies that replace existing mechanisms and run on standard classical computers.These new quantum-safe cryptography standards are expected to be deployed over the next few years. Industry and government organisations will need to be trained on how to transition their systems to use these new cryptosystems”.
