IBM takes a big new step in cryptography: practical homomorphic encryption

IBM just released an open source software package called HELib.

The HE stands for homomorphic encryption.

Although it doesn't sound terribly sexy or impressive, HELib is actually an interesting and important milestone in cryptography. HE is also a surprisingly relevant topic right now, with our ever-increasing attraction to cloud computing. Bear with me, and I'll try to explain.
