Secret Sharing for Cloud Data Security

TL;DR

This paper surveys secret sharing schemes in cloud data security, highlighting their ability to ensure privacy, availability, and integrity while enabling computations on encrypted data, within a cost-effective pay-as-you-go model.

Contribution

It provides a comprehensive review of secret sharing schemes focusing on data security, access, and cost considerations in cloud computing environments.

Findings

Secret sharing schemes effectively enforce data privacy, availability, and integrity.

They enable computation on encrypted data, enhancing security.

The survey discusses cost implications in pay-as-you-go cloud models.

Abstract

Cloud computing helps reduce costs, increase business agility and deploy solutions with a high return on investment for many types of applications. However, data security is of premium importance to many users and often restrains their adoption of cloud technologies. Various approaches, i.e., data encryption, anonymization, replication and verification, help enforce different facets of data security. Secret sharing is a particularly interesting cryptographic technique. Its most advanced variants indeed simultaneously enforce data privacy, availability and integrity, while allowing computation on encrypted data. The aim of this paper is thus to wholly survey secret sharing schemes with respect to data security, data access and costs in the pay-as-you-go paradigm.
