Preparing for the Reality of Quantum Computing Threats and Solutions

Over the next decade, the global quantum computing market is projected to grow to $12,620.7 million, bringing businesses faster, more efficient solutions. However, this technology also poses significant cybersecurity challenges. As quantum computing becomes more widespread, it could render traditional encryption modes obsolete, raising the question of how businesses should prepare. 

Identifying Potential Threats

The potential for quantum-based attacks on network encryption, cloud encryption and application security is far-reaching and could impact many sectors. The speed and efficiency that make quantum so appealing for business could enable malicious actors to decrypt vast amounts of sensitive data, including financial records, intellectual property and personal information. This could lead to significant financial losses, reputational damage and even national security threats.

The primary threat lies in the development of cryptographically relevant quantum computers (CRQCs), which could be capable of running algorithms to crack or weaken existing protections. While not yet powerful enough to pose a severe threat, its development is progressing rapidly, with some experts predicting their arrival in less than 10 years.

Researchers and organizations like the National Institute of Standards and Technology (NIST) are actively developing solutions to protect data from being stolen now and decrypted in the future when CRQCs become powerful enough. This approach is known as post-quantum cryptography (PQC).

PQC algorithms, such as those recently standardized by NIST, are designed to withstand quantum computer attacks from cryptographically relevant quantum computers. These quantum-resistant algorithms provide a defensive shield, protecting sensitive information from being compromised by future threats. PQC algorithms act as a proactive measure, protecting data from potential breaches that may occur down the line.

Future-Proofing Your Organization

While potential quantum-related threats are concerning, they should not be treated in isolation. In fact, organizations should contemplate their cryptographic agility—the ability to adapt to evolving cryptographic threats without disrupting operations – alongside their overall cybersecurity efforts.

To achieve this, leaders should focus on the following:
