A revocable attribute encryption scheme for cloud storage

Penning Zhu Zhiqiang Nate Zhihuian

Because of the large number of cloud storage users, in recent years, the problem of data security storage in cloud storage has become a hotspot because of the complexity of component and the security protection of data in cloud storage, but the traditional attribute encryption schemes have some problems, such as relatively large cipher length and complex attribute cancellation. By introducing proxy encryption technology, a revocable ciphertext attribute base encryption scheme is proposed for the above problems, and the property revocation operation is realized while shortening the cipher length, and it is proved that the CPA is safe under the DBDH hypothesis.
