Cloud Secure Storage Mechanism Based on Data Dispersion and Encryption

The widespread use and significant capability of the cloud storage service have demonstrated how important it is to the quick growth of cloud computing. However, there are still important security incidents that happen as a result of management negligence and malicious attack, resulting in the release of sizable amounts of sensitive data in the cloud storage tier. This paper proposes a CSSM, or secure cloud storage mechanism, to guarantee the confidentiality of data saved in the cloud. A technique to prevent data leakage at the storage layer was added by CSSM. Encrypted, scattered, and distributed storage is carried out via data dispersion and dispersed storage. In order to avoid the leaking of cryptographic materials, CSSM also adopted a hierarchical management strategy and coupled the user password with the exchange of secrets. The experimental findings suggest that the suggested mechanism. It can store a lot of cloud data efficiently without adding a lot of overhead, making it excellent for protecting data security in the storage layer against leaking. Users find it acceptable that it only takes 646 seconds to upload or download a 5G-size file with CSSM.
