Data sharing in cloud storage is receiving substantial attention in information communications technology, as it can provide customers with systematic and beneficial storage services. To ensure the privacy of shared confidential data, cryptographic techniques are generally applied. However, data security so far shows imperative problems in cloud storage to share data. Among them, the basic challenge is how to secure and revoke the cryptographic key. To stop this, we suggest a new data security mechanism for cloud storage that supports the following properties. The cryptographic key is ensured by the two factors. Only if one of the two factors works, the secret of the cryptographic key is maintained. The cryptographic key can be systematically revoked through the combination of proxy encryption and key separation techniques. Data is protected in detail by acquiring the attribute-based encryption technique. In addition, the security review and the execution evaluation show that our advice is safe and beneficial, respectively.
