holy_calamity writes: When (or if) quantum computers become practical they will make existing forms of encryption useless. But now researchers at Microsoft say they have made a quantum-proof version of the TLS encryption protocol we could use to keep online data secure in the quantum computing era. It is based on a mathematical problem very difficult for both conventional and quantum computers to crack. That tougher math means data moved about 20 percent slower in comparisons with conventional TLS, but Microsoft says the design could be practical if properly tuned up for use in the real world.
