Abstract

The traditional data deletion method is easily affected by a large number of approximate features in the cloud storage environment, resulting in redundant data, resulting in too long encryption and decryption time and low key availability. This paper proposed a feature iteration-based deterministic deletion method for cloud storage data. Firstly, it extracted the redundant data characteristics in cloud storage data, and classified the redundant data under cloud storage, iterated until convergence, and the realized high performance deletion of redundant data. Secondly, it used the encryption mechanism to realize the secure sharing of cloud storage data among network users. The original data ciphertext divided into residual ciphertext and sampled ciphertext. Finally, it uploaded the incomplete remaining data ciphertext to the cloud, at the same time, introduced a trusted third party to save the sampled ciphertext, realized deterministic deletion of data by destroying sampled ciphertext. The experimental results show that the proposed method takes a short time to split data ciphertext and has a high key availability of 90%, indicating that it can effectively meet the requirement of deterministic deletion of redundant data or expire data in cloud storage systems.
