An efficient secret sharing-based storage system for cloud-based Internet of Things

Abstract

Internet of things (IoTs) is the newfound information architecture based on the internet that develops interactions between objects and services in a secure and reliable environment. As the availability of art devices rises, secure and scalable mass storage systems for aggregate data is required in IoTs ons. In this paper, we propose a new method for storing aggregate data in IoTs by the use of shold secret sharing scheme in the cloud storage. In this method, original data is divided into t at each block is considered as a share. The edge server does not send these shares (blocks) through the secure channel) to cloud service providers (CSPs). Rather, the edge server hides s (blocks) with XORing two secret values and publishes the result. Indeed, with this method, 'SPs has an amount of block information. This scheme is also verifiable, i.e., in the verification ch CSP can verify its quasi-share. Moreover, before data retrieval, the edge server checks the ss of provided quasi-share from CSPs of an authorized group. Also, the proposed scheme is since new data can be inserted or part of the original data can be deleted, without changing is worth noting that the proposed scheme is more efficient compared with the other scheme vy and complex computation is not required.
