Cloud computing requires the security upgrade in data transmission approaches. In general, key-based encryption/decryption (symmetric and asymmetric) mechanisms ensure the secure data transfer between the devices. The symmetric key mechanisms (pseudorandom function) provide minimum protection level compared to asymmetric key (RSA, AES, and ECC) schemes. The presence of expired content and the irrelevant resources cause unauthorized data access adversely. This paper investigates how the integrity and secure data transfer are improved based on the Elliptic Curve based Schnorr scheme. This paper proposes a virtual machine based cloud model with Hybrid Cloud Security Algorithm (HCSA) to remove the expired content. The HCSA-based auditing improves the malicious activity prediction during the data transfer. The duplication in the cloud server degrades the performance of EC-Schnorr based encryption schemes. This paper utilizes the blooming filter concept to avoid the cloud server duplication. The combination of EC-Schnorr and blooming filter efficiently improves the security performance. The comparative analysis between proposed HCSA and the existing Distributed Hash Table (DHT) regarding execution time, computational overhead, and auditing time with auditing requests and servers confirms the effectiveness of HCSA in the cloud security model creation.

“…Some systems address techniques for secure availability through replication [14][15][16][17][18]. Recently, several remote integrity checking protocols were proposed to allow a third party auditor to check the data integrity on the remote server [19,20]. The auditor must be a trusted organization such as the government, which can provide unbiased auditing result for both data owners and cloud servers.…”

SUMMARYIn this paper, we propose solution for obtaining mutual nonrepudiation between the user and service provider in cloud storage. One of the solutions for mutual nonrepudiation is based on logging attestations, which are signed messages. For supporting write-serializability and read freshness of files, an intuitive solution is to have attestations be chain hashed. However, it is inefficient when files in an account can be accessed by multiple client devices interchangeably because client devices must keep all the attestations or there must exist a way to broadcast the last attestation to all the client devices. We propose a scheme that can guarantee mutual nonrepudiation between the user and service provider without requiring the client devices to exchange any messages, and each client device only has to store the last attestation it received. Concurrent accesses of files should be forbidden if all attestations need to be chained together with one chain. We propose to use multiple chains to provide concurrent file accesses in a single account. In addition, we also propose how to apply the hash tree to remove accumulated attestations. The results from related experiments demonstrate the feasibility of the proposed scheme. A service provider of cloud storage can use the proposed scheme to provide a mutual nonrepudiation guarantee in their service-level agreement.

Cloud computing is one of the buzzwords of technological developments in the IT industry and service sectors. Widening the social capabilities of servicing for a user on the internet while narrowing the insufficiency to store information and provide facilities locally, computing interests are shifting towards cloud services. Cloud services although contributes to major advantages for servicing also incurs notification to major security issues. The issues and the approaches that can be taken to minimise or even eliminate their effects are discussed in this paper to progress toward more secure storage services on the cloud.
