ABSTRACT:
Secure cloud storage, which is an emerging cloud service, is designed to
protect the confidentiality of outsourced data but also to provide flexible
data access for cloud users whose data is out of physical control. Ciphertext-Policy Attribute-Based Encryption (CP-ABE) is
regarded as one of the most promising techniques that may be leveraged to
secure the guarantee of the service. However, the use of CP-ABE may yield an
inevitable security breach which is known as the misuse of access credential
(i.e. decryption rights), due to the intrinsic “all-or-nothing” decryption
feature of CP-ABE. In this paper, we investigate the two main cases of access
credential misuse: one is on the semi-trusted authority side, and the other is
on the side of cloud user. To mitigate the misuse, we propose the first
accountable authority and revocable CP-ABE based cloud storage system with
white-box traceability and auditing, referred to as CryptCloud+.
We also present the security analysis and further demonstrate the utility of our
system via experiments.
