ENABLING IDENTITY-BASED INTEGRITY AUDITING AND DATA SHARING WITH SENSITIVE INFORMATION HIDING FOR SECURE CLOUD STORAGE

Abstract

With cloud storage services, users can remotely store their data to the cloud and realize the data sharing with others. Remote data integrity auditing is proposed to guarantee the integrity of the data stored in the cloud. Encrypting the whole shared file can realize the sensitive information hiding, but will make this shared file unable to be used by others. The proposed scheme is based on identity-based cryptography.
