This paper proposes a secure Cloud Storage environment without a third-party system and introduces an Improved RSA Encryption Algorithm (IREA) along with the Flexible Capacity Cuckoo Filter (FCCF) auditing technique without Third Party Auditing. The experimental results show that the proposed system has less time consumption in terms of data security.
The Cloud Environment provides storage for files as well as sharing services for disseminated clients. This technology helps users in the cloud to outsource their data and get good quality services from the cloud. Often, Data Integrity is a serious issue in Cloud Storage because the service provider is a semi-trusted one. Consequently, a self-determining auditing service is essential to check data integrity. In this paper, we developed a secure Cloud Storage environment without a third-party system and proposed an Improved Rivest-Shamir-Adleman Encryption Algorithm (IREA) along with the Flexible Capacity Cuckoo Filter (FCCF) auditing technique without Third Party Auditing. In this proposed system, the data owner encrypts the data using Improved RSA and stores it in the Cloud Service, and users alone can decrypt the data with the knowledge of the data owner. Furthermore, the FCCF ensures the integrity of the verification and secure data transactions can be provided by using the Two Level Quick Response (2LQR) code. The experimental results validate that the proposed IREA-FCCF with the 2LQR technique for data security in a CE has less time compared to that of the existing schemes in terms of encryption time, decryption time, signature generation, signature verification, and cost of the dynamic records.
