Tutanota’s PQDrive Aims to Bring Post-Quantum Cryptography to Cloud Storage, Addressing Future Threats

Concerns about data security in the face of quantum computing have not gone unnoticed. The U.S. National Institute for Standards and Technology (NIST) began working towards standardizing quantum-resistant algorithms in 2016. Virtual private network (VPN) providers, including NordVPN, are also actively exploring ways to make their services quantum-safe.

To combat the privacy and security risks associated with quantum computing, Tutanota has secured a €1.5 million grant from the German government and partnered with The University of Wuppertal to launch its latest project, PQDrive. The primary objective of PQDrive is to develop an end-to-end encrypted cloud storage solution that remains secure even in the face of quantum computers.

The envisioned product, TutaDrive, aims to combine the full sovereignty of local storage with the advantages of cloud storage. By creating a secure drive solution, Tutanota seeks to address the vulnerabilities of cloud computing, which has become a prime target for cyber threats. Recent studies indicate that approximately 90% of cybersecurity professionals are concerned about data loss, leakage, and breaches of privacy and confidentiality. Tutanota’s innovative approach aims to mitigate these risks by providing users with a secure and quantum-resistant cloud storage solution.

To achieve this, Tutanota plans to employ a hybrid encryption approach. All data stored in TutaDrive will be encrypted using both classical and post-quantum proof algorithms, providing an additional layer of protection. This approach allows the new post-quantum algorithms to prove their effectiveness over time, ensuring data security in the evolving quantum computing landscape.
