Security in the Quantum Computing Era—The POSEIDON Project Kicks Off

Quantum computers are set to revolutionise the world of technology. Their immense computing power will unlock new possibilities for data processing but will also pose serious challenges to cybersecurity. Current encryption methods will soon become inadequate. For this reason, the European Union has funded among other things the POSEIDON project, which aims to develop the tools necessary to implement post-quantum cryptography—encryption that will protect our data today and in the future.

Technological progress brings not only innovation and conveniences but also new threats. This is true for quantum computers, which are no longer just a feature of science fiction. Their capabilities are increasing, therefore, now is the time to think ahead and develop appropriate data protection mechanisms. One solution to these emerging needs is post-quantum cryptography—a new generation of encryption methods resistant to attacks using quantum computers.

Funded by the Horizon Europe programme, the POSEIDON project seeks to develop innovative cryptographic solutions and create practical tools to enable the secure storage and transmission of data in the new quantum era. The project will focus on scalable post-quantum algorithms, mechanisms for protecting data both at rest and in transit, as well as the development of recommendations and standards to facilitate the adoption of new technologies by public institutions and private organisations across Europe.

This issue affects everyone who uses digital services—from individuals to large organisations. As quantum computers become more powerful, they could easily break the encryption that currently protects passwords and sensitive data. Information held by organisations such as banks, public institutions, and healthcare providers could become vulnerable to theft. To stay secure, it’s essential to raise awareness now and prepare for the transition to quantum-safe systems.

The project’s kick-off meeting took place in Murcia, Spain, home to the project coordinator—the University of Murcia. The consortium brings together leading European research institutions and organisations specialising in digital security, including the Polish Platform for Homeland Security.

As Rashel Talukder, Managing Director of PPHS, emphasises:

The era of quantum computers is approaching, and their potential to revolutionise the way we process information poses new challenges in the field of digital security. This revolution brings significant changes that may endanger traditional cryptographic systems used to protect our data. That is why the POSEIDON project was established— to develop new post-quantum cryptographic solutions that will ensure data security in the quantum era.

As part of the initiative, PPHS will be responsible, among other things, for organising training on the implementation of post-quantum cryptography in practice, as well as for the project’s communication and dissemination activities.

POSEIDON is an initiative that combines science, technology, and purpose—to ensure that the development of new technologies goes hand in hand with the security of citizens’, public sector, and business data.
