Secure messaging provider Tutanota revealed that it is working with the L3S Research Institute at Leibniz University in Hanover on a new research project called PQmail which aims to implement computer-resistant quantum cryptography in a free messaging app.
The reason is that once quantum computers become widely available, all currently encrypted emails can be decrypted using technology. Cybercriminals currently store encrypted information to decrypt it once large quantum computers become available.
Developer and co-founder of Tutanota, Matthias Pfau explained why the implementation of quantum security encryption is essential for ensuring email security in the future, saying:
“So far, there are very few apps that use quantum encryption and no implementation for email yet. Since e-mails 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 should remain confidential in the future. “
The PQmail project is supported by EU funding and Professor Sascha Fahl and his team at USEC as well as Tutanota plan to integrate quantum secure encryption into the business messaging client to obtain a usable prototype of quantum secure messaging ready for the public.
Once completed, emails can be encrypted in such a way that they will no longer be able to be decrypted by quantum computers in the future. This is important because it means that confidential e-mail communications can no longer be read by third parties in the future.
The PQmail project plans to evaluate various post-quantum algorithms, the standardization of which is currently being tested by the National Institute of Standards and Technology (NIST). He will then design a hybrid communication protocol that supports the Perfect Forward Secrecy which can be integrated into Tutanota. Security reviews of the hybrid communication protocol will then take place before computer-resistant quantum encryption is added to Tutanota.
Once quantum secure encryption is implemented in Tutanota, businesses and consumers will be able to use it for free for additional email security.
