Efficient Cloud Storage Confidentiality to Ensure Data Security

International Journal of Engineering Research and, 2016

With the advancement of science and technology internet related communicative techniques have taken prominent roles in everyday activities. However threat of hackers and malicious groups have grown along with these advancements. It is the role of the security mechanisms to protect the sensitive data from passive and active attacks. There are different kinds of encryption algorithms to make sure that the data sent through internet is secure from any sort of attacks. Several cryptographic algorithms have been developed for encryption with each one having some advantages and disadvantages. This paper proposes an encryption technique namely AO_Enc CT to hide the nonnumeric data from the unauthorized users. The sample data are implemented in the proposed technique and the results are derived to prove that the proposed technique is higher security in protecting the data of the user.

Cloud provides storage for enterprises to store their data in virtual storage. Enterprises outsourced their data but security of data in cloud storage is not guaranteed. If anything wrong happens on the data, the users suspect the cloud storage providers. Ensuring the confidentiality of outsourced data plays a vital role in the cloud security. To ensure the confidentiality of outsourced data, this paper proposes a technique called MONcrypt. MONcrypt is based on obfuscation technique. Obfuscation is a process of masking the original text into irrelevant text without using any key unlike encryption. MONcrypt uses key for de-obfuscation. This novel obfuscation technique is used to ensure the confidentiality of outsourced data in cloud storage. The paper compares the proposed technique with existing technique like Base32, Base64, hexadecimal encoding, DES, 3DES and Blowfish. The proposed technique shows better performance and security compared with the existing techniques.

Cloud computing is the next big thing after internet in the field of information technology; some say it's a metaphor for internet. It is an Internet-based computing technology, in which software, shared recourses and information, are provided to consumers and devices on-demand, and as per users requirement on a pay per use model. Even though the cloud continues to grow in popularity, Usability and respectability, Problems with data protection and data privacy and other Security issues play a major setback in the field of Cloud Computing. Privacy and security are the key issue for cloud storage. Encryption is a well known technology for protecting sensitive data. Use of the combination of Public and Private key encryption to hide the sensitive data of users, and cipher text retrieval. The paper analyzes the feasibility of the applying encryption algorithm for data security and privacy in cloud Storage.

Cloud computing motivates organization and enterprise to outsource their data to third party cloud service provider. Some commercial cloud storage services are on-line data backup services of Amazon, and some practical cloud based software such as Memo pal, Mazy, Bitcasa, Drop box and Google have been built for cloud application. The data and software packages are stored in the cloud server. Multiple users in a group share the source code. The user can access, modify, compile and run that shared source code at any time and place. The collusion of revoked user, the cloud server will give chance to malicious cloud server data. Security issues would be provided in the public cloud storage server by encrypting the data by using encryption techniques. The scheme such as Key-Policy Attribute Based Encryption and Cipher Text-Policy Attribute Based Encryption provide security for the public storage cloud data. The Third Party Auditor maintains an audit log, keep track of malicious user details, and send back the details to the Data Owner are discussed.

In this project, we focus on cloud data storage security, which has always been an important aspect of quality of service. To ensure the correctness of users' data in the cloud, we propose an effective and flexible scheme combining cryptography and steganography. Encryption module encrypts the files before they are uploaded and decryption module decrypts them when they are downloaded. The text steganography inserts a watermark within an html file to uniquely identify it's owner. The image steganography embeds the watermark within an image file.

Virtual computing resources are provided via a cloud system that is both clever and intelligent. Based on the user's request, computing resources are made available. A hybrid cloud is the best option for storing and accessing user data for cloud deployments. Maintaining security in a hybrid cloud environment is time-consuming. This study provides a novel strategy for securing data in the hybrid cloud by ensuring the user's data is protected. Users' data in a hybrid cloud is protected using cryptographic approaches provided in this approach. Using this strategy, users' data may be protected in public and private clouds using various encryption methods. The suggested data security paradigm offers various advantages to both consumers and providers in terms of data security. Three symmetric encryption methods are offered as a service in the cloud. The concept is implemented as a cloud-based application hosted in the cloud, and the effectiveness of three strategies is assessed. They are evaluated in terms of performance and security. Using the recommended encryption methods in a hybrid cloud environment is more efficient than using other methods. The proposed technique can be used for relational data. It can be modified and enhanced to process multimedia data.

Cloud has been rising, renown, and extremely demanding innovation now a day. Cloud has wide ubiquity with its advanced features, like web access, more stockpiling, easy setup, programmed refreshes, low cost, and resource provisioning on a rent basis. Disregarding many advantages, security is viewed as increasingly significant and drew the consideration of numerous researchers. The information storage is drastically increasing, and there are many occasions that cloud doesn't ensure that data/information that has been placed in the cloud is secured from unauthorized access. Many experts are attempting to guarantee data security in the cloud, yet tragically they don't give satisfactory results. Hence we attempted to propose an effective crypto-scheme with obfuscation and cryptography for unstructured information. The scheme attempts to safeguard the secrecy of information at two phases. In the first phase, it obfuscates the file by supplanting the keywords (obfuscation), and at the subsequent phase, the obfuscated file is encoded by using the conventional RSA (Rivest Shamir Adleman) encryption algorithm for high security. Investigation results show that the proposed mechanism yields great outcomes.

Cloud computing is one of the popular method of accessing shared and dynamically configurable resources via the computer network on demand. The secure data storage on cloud environments is the primary requirement of such applications, where data are being transferred or transmitted between the servers and their users. One of the most effective techniques for secure communicating is steganography in cloud. The steganography refers to the method of writing hidden messages in a manner that no one other person but sender and receiver would be able to securely understand and communicate the information hidden in the means of communications. To ensure security of data in cloud computing, this paper presents a new text steganography approach for hide loaded secret English text file in a cover English text file. The proposed approach improved data security, data hiding capacity, and time.

In these days, storing data over the cloud has become popular. Many organizations and companies have moved to the cloud and they are continuously benefiting from its rising usefulness and convenience. Before the cloud, saving documents or information was simple. All we had to do is save them on our computer or an external hard drive but the information could not be accessible from anywhere which was resolved by cloud storage. Every process has its own pros and cons. Similarly, storing data in the cloud has many pros but is not without cons. Data could still be accessed by cybercriminals using complicated approaches, even though storing data on cloud is safe. That is the reason why every person should be cautious of their own data or information; else their information could be in the hands of data stealers who might disclose the data, if best practices are not applied. In organizations, if employees are not taught or well-informed, data can accessed by attacker. Therefore, this pape...
