What you are seeking for is a special case of secure multiparty computation, namely secure function evaluation or also called secure 2 party computation. However, general solutions to this problem require interaction, meaning that the parties performing the computation need to exchange more than two messages. You write: To compute some arbitrary ...


There are two that I know of that are pretty simple. I'll first start with one that requires a "Trusted Initializer" where we assume that there is a party Ted which is trusted by both Alice and Bob and only needs to be present for the initialization stage. This is an extension of a quantum protocol and was proposed by Rivest in Section 7. Alice holds ...
