Microsoft researchers smash homomorphic encryption speed barrier

Exclusive Microsoft researchers, in partnership with academia, have published a paper detailing how they have dramatically increased the speed of homomorphic encryption systems. With a standard encryption system, data is scrambled and then decrypted when it needs to be processed, leaving it vulnerable to theft. Homomorphic encryption, first proposed in 1978 but only really refined in the last decade thanks to increasing computing power, allows software to analyze and modify encrypted data without decrypting it into plaintext first. The information stays encrypted while operations are performed on it. This has major advantages from a security standpoint.
