4. Concepts and the proposed model

4.1. Problem formulations

We implement our model aligning with the architecture shown in Fig. 1. The input data are partitioned into functional units before they are stored. Our approach is designed to divide the sensitive data into two encrypted parts for distributed cloud storage. The main problem addressed by SA-EDS is to avoid cloud providers’ employees from reaching data without reducing the efficiency performance. We define the main problem addressed as a Security Improvement Problem in Distributed Storage (SIPDS) that is described as follows:

Definition 1Security Improvement Problem in Distributed Storage (SIPDS). Given the initial input data and storage cloud servers. The target problem is to find out a solution that can successfully store in the cloud servers and ensure the data cannot be reached by cloud operators without greatly increasing execution time.

The inputs include the initial data that consist of a string of data packets with sensitive information. The outputs are two separate data packets that will be transmitted to different cloud storage servers. The new generated data packets need to perfectly hide the sensitive information so that the cloud operators cannot read the information, even though they have the access to the data. A low level execution time of the data conversion is required.
