Hi James,
I am still not sure why you need homomorphism in this case. What is
the benefit of using homomorphism to porticor's customer, for example?
With RSA split keys, you need a trusted party to combine them - but if
the trusted party is untrustworthy, you are hosed. Presumably, with
homomorphic encryption, the trusted party would perform the operations,
but not have access to the combined key.
But I don't think this helps.
It is a way of getting around the trusted party problem, but I don't
think it does get around the trusted party problem.
