Practical applications of homomorphic encryption algorithms?
问题 It appears there there were interesting things going on in cryptography: the first homomorphic encryption scheme appeared recently (explanation, HT). Roughly speaking, it is a way of encoding x into f(x) such that you can compute f(x+y) easily knowing f(x) and f(y) even though you can't easily restore x and y (and same for f(x*y) ). What are practical applications for schemes of this type (once their security has been established)? To me, it appears they could make writing algorithms for
