Fully Homomorphic Encryption

- hype or the answer to all our prayers?

A couple of years ago, Craig Gentry produced a break-through result in cryptography: what researchers had been dreaming about for more than 25 years was finally possible: Gentry had shown how to do so-called Fully Homomorphic Encryption (FHE). What this allows is for a party A to receive encryptions of a set of inputs to some computation. A does not have the key for decryption and so has no idea what the inputs are
