I noticed this morning that Google patent search returns 189 results for the query “homomorphic encryption." I have written about homomorphic encryption in the past; it is a true mathematical breakthrough which has the potential to transform cloud computing security. But the emphasis, here, is on “potential.” There is no fully homomorphic encryption scheme which is efficient enough to be practical for real-world, general-purpose computation. This, apparently, has done nothing to stop the pate...
