In Global Survey

Cybersecurity Pros Fear a Surprise Quantum Attack yet Only 1 in 5 are Prepared

In a report issued by Dimensional Research for Cambridge Quantum, 75% acknowledge quantum attacks will defeat current encryption but only 13% have purchased products to fight the threat.

A global research survey of information security professionals released today found that most believe advancing technologies will break longstanding encryption standards within the next two years. Professionals said most organizations are currently unprepared to defend against encryption attacks but plan to be by 2023.

Conducted in October 2021 by Dimensional Research for Cambridge Quantum (now part of the newly formed company Quantinuum), the report evaluated the opinions of more than 600 cybersecurity professionals across industry and government.


Key highlights include

  • 70% of respondents expect new and evolving technologies will compromise existing encryption approaches
  • 75% acknowledged that quantum-enabled attacks will defeat current encryption techniques
  • 80% of respondents are worried that a quantum-enabled attack could occur “without warning”
  • 86% confirm they adhere to regulations requiring critical data protection for an extended period with nearly half needing to protect data for five years or more. Data that must be secured over time is vulnerable to “hack now, decrypt later” tactics currently being employed by adversaries who will use powerful quantum computers when available.

The report found that only 21 percent of security professionals surveyed feel prepared for advancing encryption attacks while another 38 percent say their organizations will be ready within the next two years. However, just one in five indicate any budget allocation to address the issue and even fewer have started researching quantum threats and possible solutions.

With nearly half indicating they are quantum security knowledgeable, the key challenges cited in building a quantum defense include lack of in-house expertise, immature solutions, and undefined post-quantum encryption algorithms. Just 13 percent have purchased a solution to start enabling a quantum defense.

“Cybersecurity professionals appear to appreciate the advancing threat to current encryption standards and say they will be ready in time. However, there appears to be little real movement within organizations towards preventing a potentially catastrophic loss of critical data, despite the associated financial and legal consequences,” said Duncan Jones, head of quantum cybersecurity for Cambridge Quantum.

Jones said the strategy being implemented by adversarial nations and other bad actors to steal encrypted communications today for later decryption with quantum computers should especially concern those organizations required to protect critical data over several years or more. 86% of respondents confirm they adhere to regulations requiring critical data protection for an extended period with nearly half needing to protect data for five years or more.

“Organizations with data in the cloud or IoT devices in the field should move quickly to strengthen encryption against existing threats as well as those posed by quantum attackers in the future,” Jones said. “Financial institutions, healthcare, governments and other entities protecting critical data should ensure their security foundation is as strong as possible today, as well as future-proofed for tomorrow.”

Jones said organizations can move towards using post-quantum algorithms, such as those being standardized by the NIST post-quantum cryptography process, as well as consider bolstering current encryption defenses by leveraging quantum-enhanced cryptography.
