Abstract: Attribute-based encryption (ABE) is the most effective access control mechanism for protecting the cloud storage environment. The data of the data owner are separated into two distinct security levels and kept in various cloud providers according to our plan, which results in an increase in the degree of security that is provided by outsourcing data. Furthermore, our system, which is based on ciphertext-policy attribute-based encryption (CP-ABE), is able to not only offer a fine-grained access control for the data user, but it can also totally leverage the cloud side to permit outsourcing decryption. For the purpose of ensuring security, the FHE model achieved a gain of 88%, the AES approach achieved a gain of 81%, the RSA model reached 92%, and the PHE technique achieved 94%. A security level of 99.74% was obtained by the ALO-DHT model that was built. The ALO-DHT model that was built was successful in achieving 99% secrecy.

Keywords: attribute-based encryption; multi-cloud; outsourcing decryption; access control.
