The strength of current cryptography relies on the difficulty of tasks like factoring prime numbers and finding discrete logarithms. However, quantum computing threatens this reliance by potentially making these problems easier to solve, which could compromise online security. Deirdre Connolly is developing post-quantum cryptography to address potential vulnerabilities and ensure digital privacy against advancing technology. This involves exploring new methods of protection and preparing for various attack scenarios, such as 'Harvest Now, Decrypt Later' attacks. The transition to a post-quantum era aims to be seamless for end users, minimizing visible impacts on their experience.
Cryptography that protects our privacy relies on the infeasibility of factoring prime numbers and finding discrete logarithms for current computing methods. Quantum computing could change that, potentially threatening digital security systems that rely on these complex mathematical challenges. Preparation for post-quantum cryptography is essential to strengthen digital defenses, enabling new methods for protecting information against future technological advances.
Deirdre Connolly emphasizes that while quantum computing's full potential is uncertain, addressing post-quantum cryptography now is crucial. This proactive approach will help secure existing encryption methods and develop new protection strategies against potential future attacks.
