IBM researchers are working with the developers of the secure messaging platforms Signal and Threema to design cryptographic systems that can resist future quantum computer attacks.
The collaborations aim to adapt messaging protocols and encryption schemes so that private communications remain secure once quantum machines become powerful enough to break today’s widely used cryptography.
The initiative aims to curb the risks posed by the so-called “harvest now, decrypt later” threat, in which attackers steal encrypted data today and store it until future advances in computing allow them to decrypt it.
The work is carried out by a team of IBM Research cryptographers led by principal research scientist Vadim Lyubashevsky, in collaboration with engineers from the Signal Foundation. Their findings are being presented at the Real-World Crypto (RWC) conference, a prominent venue where academic and industry experts discuss practical cryptographic…
