However, businesses should think carefully about the possibilities and impact of transformative technologies like quantum computers, and how these technologies help shape the future. Quantum computers could potentially spur breakthroughs in healthcare, financial strategies and security, since they can provide the processing power to solve problems that our current computers cannot. Riaan de Villiers, cybersecurity expert and business analyst at LAWTrust, says the major benefit is that quantum computers could process information much faster than current (traditional) computers. Processing that will take traditional computers years to perform could theoretically be completed by a quantum computer in a matter of hours. Herein lies the crux … Cybercriminals make their living by attacking businesses and people around the world. Technologies such as quantum computing can create an opportunity for cybercriminals to execute even more catastrophic cyber-attacks. Traditionally, Public Key Infrastructure (PKI) secures organisations. As long as cybercriminals do not know what your keys (encryption and/or decryption) are, your data is safe. However, quantum computing can change that. In cybersecurity there is a cyber-attack called a brute-force attack, for example, where attackers can try to guess your key. By checking every possible value, the attacker would eventually be able to guess your key. However, with the current technology, to guess all possibilities for keys would take hundreds of years, which makes brute-force attacks impractical. Since quantum computers will be much faster, they can, theoretically, guess an encryption and/or decryption key in a matter of hours. De Villiers says there is still much speculation about what the post-quantum world would be like, “but organisations can start preparing for when the inevitable comes.” Even though readily available quantum computers are still in the distant future, organisations can start thinking about their strategy to become more crypto-agile. To prepare for the world of quantum computing, organisations can: • Create a crypto inventory. A list of cryptographic algorithms in use will help organisations identify vulnerable algorithms and migrate them to quantum-resistant algorithms when it becomes necessary. • Start building your systems with crypto-agility in mind. For example, when applying digital signatures, use PAdES (PDF Advanced Electronic Signatures) compliant standards that will allow you to re-timestamp your documents with quantum-resistant algorithms. • Ask your third-party platform providers what they are doing to prepare for the post-quantum world.
