Outsourcing Secure Two-Party Computation as a Black Box
Secure multiparty computation (SMC) offers a technique to preserve functionality and data privacy in mobile applications. Current protocols that make this costly cryptographic construction feasible on mobile devices securely outsource the bulk of the computation to a cloud provider. However, these outsourcing techniques are built on specific secure computation assumptions and tools, and applyin...

متن کاملA New Approach to Black-Box Concurrent Secure Computation
We consider the task of constructing concurrently composable protocols for general secure computation by making only black-box use of underlying cryptographic primitives. Existing approaches for this task first construct a black-box version of CCA-secure commitments which provide a strong form of concurrent security to the committed value(s). This strong form of security is then crucially used ...
متن کاملSecure computation outsourcing
Computation outsourcing is used when an entity needs to execute a task but does not have the appropriate computation power to perform it. In this paper, we will survey the approach of delegation: instead of doing the computation locally, the entity outsources it to one or more external helpers which have the appropriate resources. Although this can safely be done for most everyday life tasks, i...
متن کاملBlack - Box Constructions for Secure Computation ∗ ( extended abstract )
It is well known that the secure computation of non-trivial functionalities in the setting of no honest majority requires computational assumptions. We study the way such computational assumptions are used. Specifically, we ask whether the secure protocol can use the underlying primitive (e.g., one-way trapdoor permutation) in a black-box way, or must it be nonblack-box (by referring to the cod...
