Quantum Computing: Threats and Opportunities for Information Security in the Digital Age

Telefónica is developing a technological infrastructure called Quantum Safe Networks, which combines classic cryptography with post-quantum algorithms to protect against potential quantum attacks. The company has collaborated with Vithas hospital group to deploy a quantum network to secure sensitive medical data, and has launched a Quantum Safe connectivity solution for industrial IoT devices with IDEMIA and Quside. Telefónica has also presented a demo of private 5G networks with post-quantum encryption for critical environments.

Telefónica is spearheading efforts to develop a technological infrastructure called Quantum Safe Networks, integrating classic cryptography with post-quantum algorithms to safeguard against potential quantum attacks. This strategic initiative underscores the company's commitment to future-proofing its digital infrastructure against the looming threat of quantum computers.

The company's collaboration with Vithas hospital group to deploy a quantum network for securing sensitive medical data exemplifies its proactive approach to data protection. Additionally, Telefónica has partnered with IDEMIA and Quside to launch a Quantum Safe connectivity solution for industrial IoT devices. This solution aims to enhance the security of critical industrial applications by leveraging post-quantum encryption.

Further, Telefónica has demonstrated the potential of private 5G networks with post-quantum encryption for critical environments. This innovation showcases the company's ability to integrate advanced cryptographic techniques into emerging technologies, ensuring robust security for next-generation networks.

The post-quantum cryptography (PQC) market is expected to experience significant growth, with revenue forecasted to surpass $480.1 million in 2025 and continue to grow through 2035 [1]. This growth is driven by the urgent need for quantum-resistant solutions to protect against the threat posed by quantum computers to classical encryption methods such as RSA and ECC.

However, the implementation of PQC solutions faces challenges, particularly in integrating these algorithms into existing IT infrastructures. Legacy systems and the complexity of updating cryptographic protocols present significant hurdles, especially in sectors where data security is paramount but operational continuity is critical [1].

The impact of U.S. trade tariffs on the global PQC market has introduced additional complexity, increasing production costs and disrupting supply chains. While these tariffs pose immediate financial and operational challenges, they also catalyze domestic innovation and reshoring of manufacturing capabilities, reshaping the competitive landscape [1].

Telefónica's Quantum Safe Networks initiative aligns with the broader market trends and addresses the critical need for quantum-safe cybersecurity infrastructure. As the PQC market continues to grow, companies like Telefónica that invest in future-proofing their technologies will be well-positioned to capitalize on the opportunities presented by this evolving landscape.
