Quantum computing not only has the potential to vastly increase computational power, but it also poses a significant risk to current security and cryptography systems, according to Professor Dr. Tanja Lange from the Eindhoven University of Technology.
Cryptography, which ensures privacy and security in various data transactions, could be compromised as quantum computing progresses. This could lead to an increase in espionage, data manipulation, and the possibility of manipulating conversations.
In an effort to raise awareness about cybersecurity and promote action, Lange participated in a podcast organized by Matthias J. Kannwischer, the director of the Secure Quantum Migration Center at Chelpis.
Cryptography, which underlies many applications and web browsers, plays a crucial role in maintaining privacy and security in everyday life. It ensures the privacy of SMS messages, secure internet browsing, secure online banking, and even transactions at ATMs. Losing the protection of cryptography would have a significant impact on these data transactions that we currently take for granted.
While quantum computing is still in its early stages, there is already concern about the threat of “collect now, decrypt later.” Hackers and state-sponsored actors are actively collecting data using supercomputers for future use.
To address this threat, cryptographers have been developing post-quantum secure cryptographic standards since 2008. These standards are divided into four main categories: code-based, isogeny-based, lattice-based, and multivariate quadratic-based. Each category becomes more complex and advanced.
Security companies are actively working on migrating to post-quantum computing to enhance security before the arrival of quantum computers. National-level standards and licenses are also being implemented to ensure optimal cybersecurity. For example, the United States has set a deadline of 2033 for government-affiliated companies to implement post-quantum security measures.
Europe, through the European Union Agency for Cybersecurity (ENISA), also has similar standards, although decisions on cybersecurity remain the responsibility of individual countries. France, for example, is working on a certification system for post-quantum cryptography.
In conclusion, the advent of quantum computing poses significant threats to security and cryptography systems. However, efforts are being made to develop post-quantum secure cryptographic standards and improve cybersecurity measures.
