Quantum Computers Pose Threat to Email Safety, But Solution Is on the Way

With the potential to perform more advanced calculations and create more complex processing networks, quantum computers also pose new risks of compromising the most sophisticated cybersecurity systems. To address this issue, the team behind end-to-end encrypted email software Tutanota and the Leibniz University of Hannover have jointly begun a dedicated research project. The parties claim to develop a quantum computer resistant cryptography to protect Tutanota email application users against potential decryption of all currently encrypted emails. Tutanota explained to “Quantum computers do […] pose a serious threat to cryptography as the asymmetric cryptosystems that are widely used today (RSA, (EC)DSA and (EC)DH), rely on variants of only two hard mathematical prob...
