Secure Data Outsourcing in the Cloud Using Multi-secret Sharing Scheme (MSSS)

In the last few years, the demand of data outsourcing in the cloud has enormously increased. However, there are some significant barriers to cloud computing adoption. One of the most significant barriers of outsourcing data in the cloud computing is its security issues especially when sensitive data such as personal profile, financial records, medical reports, etc. are outsourced on cloud servers. Therefore, strong security measures are essential to protect data within the cloud. Recently, secret sharing schemes have been applied to protect sensitive data in cloud storage. In this paper, we propose a (t, n) multi secret sharing scheme (MSSS) for secure data outsourcing in the cloud. In the proposed scheme, t secrets are divided into n shares, which are distributed to n cloud servers (one share per server) and a trusted user can recover all secrets by combining shares from at least t servers. The analysis shows that the proposed scheme can provide secure and efficient data outsourcing system in the cloud.
