Experts say the main problem is not that quantum computers will break current encryption systems now, but that data is being stolen to be decrypted later when the technology is better.

This tactic is called 'Harvest Now, Decrypt Later'. Hackers gather encrypted data now and store it for years. When quantum computers can crack common encryption, this data could be decrypted quickly.

For companies, this threat is different from traditional cyberattacks. Before, data theft caused immediate damage. But with quantum computers, companies might not know their data has been copied and stored for later use.

The most valuable data is the kind that lasts a long time. This includes technology secrets, product designs, and business plans.

The risk is not just for individual companies. Many businesses are connected through digital platforms, which can spread the risk.

If one link in the supply chain is compromised, data from many organizations could be stolen and used for future attacks.

Quantum computing will be a big breakthrough, but it also poses big challenges for cybersecurity. Vietnam needs to take steps now to avoid future threats.

Vietnam cannot ignore the quantum race.

Quantum technology is seen as a key technology that will change science, technology, and the economy in the coming decades.

However, it is a very complicated field that requires advanced research and skilled talent.

According to Tran Hong Thai, many research areas are still experimental and not ready for commercial use.

He said Vietnam should invest in quantum research now so it can master the technology instead of just adopting it later.

Quantum computing could break current encryption.

Quantum technology also poses big challenges to cybersecurity.

Once quantum computers are powerful enough, many current encryption systems might not be safe.

The main concern is that attackers could collect encrypted data now and decrypt it later when they have the technology.

Senior Colonel Nguyen Hong Quan said Vietnam's digital transformation is happening fast, making digital technology crucial.

At the same time, cyberattacks are becoming more sophisticated and cross-border. Cybercriminals are using AI for fraud and attacks.

The advancement of quantum computing is an additional challenge to security systems. Many encryption methods might not be able to protect data against future quantum computers.

Quan said the challenge is not just to respond to current cyber threats but also to build cybersecurity for the quantum era.

Major General Nguyen Tung Hung noted that the world is entering the age of AI and quantum technologies. Vietnam must prepare for the 'Harvest Now, Decrypt Later' strategy.
