Quantum computing is an exciting breakthrough, but it poses a serious threat to cybersecurity. While today’s encryption techniques protect sensitive data, quantum computers could make them easy to crack, opening the door to new types of attacks.
Here’s a look at how quantum computing impacts encryption and what steps organizations should take to prepare.
Why quantum computing puts encryption at risk
Quantum computers use qubits, which can represent both 0 and 1 at the same time, allowing them to solve complex problems much faster than traditional computers. This could break the encryption methods we depend on today.
Encryption like RSA and ECC, which would take current computers decades to crack, could be broken by a quantum computer in seconds. The Quantum Threat Timeline Report suggests that by 2030, quantum computers could compromise modern encryption, risking sensitive information such as financial records and government data.
Potential impact on data security
As quantum computing advances, encrypted data across industries may be exposed. A Global Risk Institute report indicates that 50% of companies in finance, healthcare, and government see quantum computing as a major cybersecurity threat. Hackers could use it to access sensitive information, from bank details to government secrets.
This threat includes stored data; attackers may steal encrypted data now to decrypt it later, a tactic known as “store now, decrypt later.” According to DigiCert, over 80% of cybersecurity professionals are worried about this long-term risk.
Steps organizations can take to prepare
Quantum computing may still be a few years away from becoming mainstream, but businesses and governments are already preparing for this threat. Organizations can take the following important measures:
1. Start Learning About Quantum-Safe Encryption: Quantum-safe encryption (also called post-quantum encryption) is being developed to resist attacks from quantum computers. The National Institute of Standards and Technology (NIST) is working on creating new encryption standards that are expected to be ready by 2024. Organizations should stay updated on these standards and plan to adopt them as they become available.
2. Evaluate The Risks And Sensitivity Of The Data: All data isn’t equally sensitive. A study from Gartner predicts that 60% of organizations will have assessed their quantum vulnerabilities by 2025. Identifying which types of data would be most at risk if decrypted by a quantum computer helps prioritize what needs the strongest protections.
3. Practice “Crypto-Agility”: Crypto-agility is about being ready to switch to new encryption methods as they become available. A survey by Entrust found that 54% of businesses are already taking steps toward crypto-agility, meaning they’re preparing systems that can adapt to different types of encryption.
4. Monitor Developments in Quantum Computing: Quantum computing technology is evolving quickly. Regularly monitoring advancements allows organizations to adjust their security strategies in real-time, keeping up with changes in the quantum field. 71% of global organizations plan to increase their investment in quantum-safe security by 2026, according to a report by Accenture.
5. Work with Experts: Specialized knowledge is needed to prepare for quantum computing. Consulting with experts in cybersecurity and quantum-safe encryption can help organizations build a roadmap to tackle these challenges. The Quantum-Safe Security Working Group recommends all organizations consider professional assessments to develop quantum-resilient strategies.
