'Visions of a fully homomorphic cryptosystem have been dancing in cryptographers' heads for thirty years. I never expected to see one. It will be years before a sufficient number of cryptographers examine the algorithm that we can have any confidence that the scheme is secure.' -- Bruce Schneier Even without PRISM, the rise of cloud computing is a strong incentive for people to try to develop practical homomorphic encryption.
