DLAS: Data Location Assurance Service for cloud computing environments

In this paper, we present a Data Location Assurance Service (DLAS) solution for the well-known, honest-but-curious server model of the cloud computing environment; the proposed DLAS solution facilitates cloud users not only to give preferences regarding their data location but also to receive verifiable assurance about their data location from the Cloud Service Provider (CSP). Our proposed DLAS solution is based on cryptographic primitives such as zero knowledge sets protocol and ciphertext-policy attribute based encryption. According to the best of our knowledge, we are the first to propose a solution of this kind.
