• Flawless and resilient email technology is on the way

Secure messaging provider Tutanota revealed that it is working with the L3S Research Institute of the Leibniz University in Hannover on a new research project called PQmail that aims to implement computer-resistant quantum cryptography in a free messaging application. The reason is that once quantum computers are widely available, all currently encrypted emails can be decrypted using technology. Cybercriminals currently store encrypted information in order to decrypt it once large quantum computers become available. Tutanota developer and co-founder Matthias Pfau explained why the implementation of quantum strong encryption is essential to ensure email security in the future, saying: "So far, there are very few applications that use quantum encryption and still there is no implementation for email. Since emails in particular are so important for professional and confidential communication, it is essential that we find a secure solution here as quickly as possible. More and more professional emails are encrypted from start to finish This confidential communication must remain confidential in the future."

PQmail project

The PQmail project is supported by EU funding and Professor Sascha Fahl and his USEC team, as well as Tutanota's plan to integrate secure quantum encryption into the company's email client to prototype email. quantum safe usable ready for the public. Once completed, the emails can be encrypted in such a way that they can no longer be decrypted by quantum computers in the future. This is important because it means that confidential email communications can no longer be read by third parties in the future. The PQmail project plans to evaluate several post-quantum algorithms, the standardization of which is currently being tested by the National Institute of Standards and Technology (NIST). You will then design a hybrid communication protocol that supports Perfect Forward Secrecy that can be integrated into Tutanota. Hybrid communication protocol security reviews will take place before computer-resistant quantum encryption is added to Tutanota. Once strong quantum encryption is implemented in Tutanota, businesses and consumers will be able to use it for free for added email security.
