Research into applied cryptography is generally spread across universities and not always connected to real systems. @3miLabs, founded by cryptographer @TomerAshur and associated with @KU_Leuven's @CosicBe lab, addresses this by bringing researchers directly into client teams. [...] “Privacy and security are not optional in systems that hold real value. When cryptography fails, it usually fails silently and irreversibly. Only a few hundred researchers worldwide can design these schemes and prove they hold, and 3MI Labs brings a group of them under one roof,” adds Jakob Lingg, partner at Vsquared Ventures.
