Storage cloud scheme, pushing data to the storage cloud poses much attention regarding data confidentiality. With encryption concept, data accessibility is limited because of encrypted data. To secure storage system with high access power is complicated due to dispersed storage environment. In this paper, we propose a hardware-based security scheme such that a secure dispersed storage system using erasure code is articulated. We designed a hardware-based security scheme with data encoding operations and migration capabilities. Using TPM (Trusted Platform Module), the data integrity and security is evaluated and achieved.

Cloud computing is a way to increase the capacity dynamically without investing in new infrastructure, training new users as well as licensing new software. The increasing popularity of cloud storage services has lead companies that handle critical content to think about using these services for their daily storage needs. Power systems records, huge Medical datasets and financial content are partial critical content that could be moved to the cloud. To this, cloud storage providers reveal challenges in achieving content availability, reliability, storage overhead and content integrity that require high efficiency on single cloud storage architecture. Cloud storage disperses content blocks over single cloud storage nodes. This study proposes Reliable Multi-Cloud Storage Architecture (RMCSA) based on Erasure Codes, that content can be dispersed to different cloud storage providers to reduce challenges which lead to Lock-In. A Multi-Cloud Control Node will manage other Control Nodes evolved in the cloud as well as service migration across sub-clouds. Currently, replication is the most applied technique which disperses content replica but standing against content loss becomes critical, hence ineffective. To assure stability in storage costs with best practice to assure content failure or loss recovery, we applied a Maximum Distance Separable such as Reed-Solomon to our RMCSA. Analysis shows that RMCSA resolves a number of storage issues and recommends Zfec library as erasure code emulator due to its accuracy.

In cloud storage systems, data security management is becoming a serious matter. Big data and accessibility power is increasingly high, though the benefits are clear, such a service is also relinquishing users' physical possession of their outsourced data, which inevitably poses new security risks toward the correctness of the data in cloud. As a result, cloud storage security has become one of the driving components in Cloud Computing regarding to data manipulation trust on both hosting center and on-transit. This paper proposes a TPM-Based Security over Multi-Cloud Storage Architecture (MCSA) grounded on Erasure Codes to apply root of trust based on hardware authenticity. An erasure codes such as Reed-Solomon, is capable of assuring stability in storage costs with best practice to guarantee data accessibility failure recovery. A Multi-Cloud Control Node manages other Control Nodes evolved in the cloud; this work introduces TPM-Based Security functions per Control node in the architecture. This concept will resolve a number of storage security issues, hence Cloud Computing adoption.
