Homomorphic Encryption paper scoops IBM Research Award

This paper represents a large step forward in the advancement of fully- homomorphic encryption. It describes optimizations that allow for a fully-homomorphic implementation of a complex and practical circuit, the AES encryption algorithm. The optimizations are both AES-focused and applicable more generally to future implementations of fully-homomorphic circuits. They reduced the running time of a circuit like AES by roughly two orders of magnitude, down to 36 hours to compute the encryption of a single AES block. Other optimizations that process multiple blocks simultaneously achieve an amortized rate of just over five minutes per block, reducing the running time from around 150 days, to five minutes. To note a few of the contributions of the work: strategies for minimizing costly operations that are unique in fully-homomorphic encryption; new ways of structuring algorithm...
