This paper reports the design of a cloud-based service for coordinating secure outsourcing of storage and computation of scientific data, particularly matrices. While this service may support different secure outsourcing protocols and mechanisms (e.g. homomorphic encryption, secret sharing and randomization), we hide all the complexity from end-users and move it to a middleware broker. The broker manages the communication between the client and one or more clouds. The requests submitted by users are automatically translated into WS-BPEL workflows and then executed by the broker workflow engine to coordinate the control flow and the data flow for outsourcing of matrix operations. We detail the architecture of our framework and the design of its key components. Our work facilitates real-world and practical deployment of recently proposed secure outsourcing protocols.
