Quantum technology 2025: This is how Germany protects the digital future!

In today's digital world, quantum computing is becoming increasingly relevant. On the occasion of the international year of quantum science and technology, which was called out by the United Nations for 2025, it becomes clear how important progress in this area is for science, security and global systems. According to The Fast Mode , the value of quanta technologies could rise to impressive 1.3 trillion US dollar. But while opportunities open up, the advent of quantum computers also raises serious questions about the security of existing digital systems, especially in cryptography.

One of the greatest challenges is the threat from quantum computers that could make traditional encryption standards such as RSA and ECC superfluous in the near future. The practice of the "Harvest Now, Decrypt Later" - in which attackers collect encrypted data in order to later decipher it with powerful quantum computers - makes it urgently needed that both the public and the private sector take measures to protect digital transactions from these future threats.

the need for a change

The transition to post quantum cryptography (PQC) is not only desirable, but necessary. Between 2023 and 2025, important progress in the standardization of quantum-resistant algorithms is on the plan, such as Silicon Trust . The National Institute of Standards and Technology (Nist) will finalize three new algorithms in August 2024 to secure key exchange and digital signatures: Crystals-Kyber, Crystals dilithium and Sphincs+.

These algorithms are based on mathematical problems that are considered quantum -resistant. In addition to the new approaches, alternative procedures such as Falcon and Mceliece are also becoming more important, and the integration of cryptographic agility is becoming increasingly important in order to be able to react flexibly to threats. However, there are challenges, such as the high resource requirement of the new algorithms and the need to adapt existing systems.

global efforts and progress

A strategic timetable is crucial to make the transition to post quantum cryptography. Governments worldwide, including the USA and the EU, are actively committed to developing and implementing PQC standards. While the United States has stated that companies have to switch to PQC by 2035, the EU is pursuing an ambitious strategy for providing quantum cryptography networks with the EuroQCI initiative to ensure the safety of digital communication.

China also invests vigorously in quantum technologies and integrates PQC into their 5G and IoT networks. Innovative approaches such as the quantum key distribution (QKD), which were presented thanks to the Micius satellite, show the potential to offer quantum computing for security, even if there are still challenges in scaling.

The way to the future

The challenges of implementing PQC require continuous research and development. It is not only important to identify cryptographic weaknesses, but also to advance the implementation of existing systems, which is often complex and time -consuming. In addition, the global standardization, which is essential for interoperability, remains a big topic that needs to be addressed.

Another aspect that will be decisive for the resilience of digital platforms in the future is the ability to adapt cryptographic systems quickly and safely. The BSI emphasizes that post-quante cryptography processes comprises that are considered safe against quantum attacks and can be implemented on classic hardware. At a time when digital security has a top priority, it is necessary to integrate these technologies and to join the global standardization efforts.
