TECHNOLOGY & CYBERSECURITY — Israel has launched a new consortium focused on developing communications networks that can remain secure in an era when powerful quantum computers could threaten some of today's encryption systems.

The initiative brings together researchers, technology companies and other organisations to develop and test technologies designed to protect sensitive communications against future quantum-powered attacks.

The effort reflects growing concern among governments and businesses that advances in quantum computing could eventually make some widely used cryptographic methods vulnerable.

Why Quantum Computers Matter for Cybersecurity

Today's internet depends heavily on mathematical encryption to protect banking transactions, government communications, business information and personal data.

Some of the cryptographic systems currently in widespread use rely on mathematical problems that are extremely difficult for conventional computers to solve.

A sufficiently powerful quantum computer, however, could solve certain of these problems far more efficiently.

This creates a long-term security challenge for governments and technology companies.

Israel Wants to Prepare Before the Threat Arrives

The new consortium is intended to help Israel prepare for a future in which quantum computers become capable of attacking currently protected communications.

Rather than waiting until quantum computers reach that level of capability, researchers are working on security technologies that can be deployed ahead of time.

This approach is commonly known as post-quantum cybersecurity.

What Is Post-Quantum Cryptography?

Post-quantum cryptography involves encryption methods designed to resist attacks from both conventional computers and future quantum computers.

Researchers around the world are developing and evaluating new mathematical approaches that could replace vulnerable encryption systems.

The transition is expected to take years because organisations operate enormous numbers of computers, networks and connected devices.

Replacing cryptographic systems across those environments requires careful planning and testing.

Communications Networks Are a Major Target

Modern communications networks carry enormous amounts of sensitive information.

Government agencies, financial institutions, hospitals, businesses and individuals all depend on secure digital communications.

A successful attack against critical communications infrastructure could have consequences far beyond the theft of individual pieces of information.

This makes the protection of national communications networks an important part of long-term cybersecurity planning.

The Risk of Harvest Now, Decrypt Later

One of the concerns surrounding quantum computing is the possibility of "harvest now, decrypt later" attacks.

In such a scenario, attackers could collect encrypted information today and store it until sufficiently powerful quantum computers become available.

If the encryption protecting that information can eventually be broken, previously collected data could become readable.

This is particularly concerning for information that must remain confidential for many years.

Israel Has a Strong Cybersecurity Industry

Israel has developed a major technology and cybersecurity ecosystem, with companies and research institutions working on network security, encryption, artificial intelligence and advanced computing.

The country's experience in cybersecurity provides a foundation for developing technologies designed to address emerging threats.

The new consortium brings together expertise that could help accelerate research and practical testing.

Quantum-Safe Networks Could Become Essential

Businesses and governments are increasingly examining how their existing systems would respond to a future quantum threat.

Some organisations are beginning to inventory their encryption systems and identify information that requires long-term protection.

The objective is to begin the transition before quantum computers become powerful enough to create an immediate security crisis.

Quantum Technology Is Also an Opportunity

Quantum computing is not only a cybersecurity threat.

The technology could eventually provide major advances in areas such as materials science, drug discovery, optimisation and scientific research.

This creates a complicated situation for governments.

They must encourage quantum research while simultaneously preparing their digital infrastructure for the security risks that powerful quantum computers could create.

The Transition Will Not Be Simple

Moving to quantum-resistant security will require more than installing a new piece of software.

Encryption is embedded throughout modern technology, including websites, mobile applications, cloud systems, financial networks, industrial equipment and government infrastructure.

Organisations will need to identify vulnerable systems, select appropriate replacement technologies and ensure that different systems can continue communicating securely during the transition.

International Cooperation Will Matter

Cybersecurity threats do not stop at national borders.

Communications between countries, companies and cloud providers often pass through interconnected international networks.

As a result, quantum-safe security standards will need to work across different jurisdictions and technology platforms.

International standards and cooperation could therefore play an important role in the transition.

What This Means for Businesses

Companies should not wait for quantum computers to become commercially powerful before considering the problem.

Organisations holding sensitive information for long periods may have particular reasons to begin preparing early.

Understanding where encryption is being used, what algorithms protect important information and how those systems can eventually be upgraded can reduce the risks associated with a future transition.

What This Means for the Future of the Internet

The development of quantum-safe communications could become one of the most important cybersecurity transitions of the coming decades.

The internet was not originally designed around the possibility of powerful quantum computers, meaning some fundamental security assumptions may eventually need to change.

Countries that prepare early could have an advantage in protecting critical infrastructure and sensitive information.

Our Perspective

Quantum computing may still be years away from posing the worst-case cybersecurity threat, but waiting until the technology arrives would be a dangerous strategy.

Security systems take years to design, deploy and replace, while sensitive information can remain valuable for decades.

Israel's new consortium reflects a broader shift in cybersecurity: preparing for tomorrow's computing power before it becomes today's security crisis.

Conclusion

Israel's new communications-security consortium aims to develop technologies capable of protecting networks against the future threat posed by powerful quantum computers.

The initiative highlights the growing importance of post-quantum cybersecurity as governments and businesses begin preparing for a major change in computing technology.

The challenge will be developing solutions that are not only resistant to quantum attacks but also practical, affordable and compatible with the enormous infrastructure that powers modern communications.

The quantum era has not fully arrived, but the race to secure the digital world before it does has already begun.
