thesis Cloud Computing & Security final.doc
A cloud is the powerful combination of cloud computing, storage, management solution. More and more turning to data storage, management in the cloud computing & Security. It is often provided "as a service “over the Internet, typically in the form of infrastructure as a service (IaaS), platform as a service (PaaS), or software as a service (SaaS). Cloud computing is a general term for anything that involves delivering hosted services over the Internet. Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides secure, resizable compute capacity in the cloud. It is designed to make web-scale cloud computing easier for developers. In this thesis paper we analysis about AWSEC2 and GCE and compare both which is better. Amazon EC2 reduces the time required to obtain and boot new server instances to minutes, allowing you to quickly scale capacity, both up and down, as your computing requirements change. Google Compute Engine lets you create and run virtual machines on Google infrastructure. Compute Engine offers scale, performance, and value that allow you to easily launch large compute clusters on Google's infrastructure. There are no upfront investments and you can run thousands of virtual CPUs on a system that has been designed to be fast, and to offer strong consistency of performance. Arguably, Infrastructure as a Service (IaaS) is the most important cloud computing vertical. Within that, in terms of services and features, AWS enjoys the top position, while Google Cloud Platform is slowly catching up. In this post, we’ll discuss major differences between Amazon’s EC2 and Google Compute Engine (GCE). This paper we proposed a method by implementing RSA algorithm will explore data security of cloud in cloud computing by implementing digital signature and encryption with elliptic curve cryptography.

In today's modern IT everything is possible on the web by cloud computing, it allows us to create, configure, use and customize the applications, services, and storage online. The Cloud Computing is a kind of Internet-based computing, where shared data, information and resources are provided with computers and other devices on-demand. The Cloud Computing offers several advantages to the organizations such as scalability, low cost, and flexibility. In spite of these advantages, there is a major problem of cloud computing, which is the security of cloud storage. There are a lot of mechanisms that is used to realize the security of data in the cloud storage. Cryptography is the most used mechanism. The science of designing ciphers, block ciphers, stream ciphers and hash functions is called cryptography. Cryptographic techniques in the cloud must enable security services such as authorization, availability, confidentiality, integrity, and non-repudiation. To ensure these services of security, we propose an effective mechanism with a significant feature of the data. This paper is to show how to improve the security of the Cloud storage using the implementation of a hybrid encryption algorithm and hash functions. It proposes the implementation of two algorithms, Rivest-Shamir-Adleman (RSA) and Advanced Encryption Standard (AES) with a secure hashing algorithm (SHA256) by using Netbeans IDE 8.0.2, JDK 1.7 tool and EyeOS2.5 as a cloud platform on ubuntu14.04.

Abstract— Current security scheme in cloud computing applied single encryption algorithm. However, usage of a single algorithm is not effective for high-level security requirement towards data processing in cloud computing. Therefore, this study proposes combination of AES, ECC and RSA encryption method to strengthen the security in cloud in terms of authentication and encryption. The method for this study is the text data has been encrypted using AES then, AES key have been encrypted by ECC only after that RSA will encrypt both the ciphertext and the encoding key again. Java NetBean is used to program the evaluation tool to calculate the performance of the encryption method. First, the tool has applied the three algorithms AES, ECC and RSA using a dataset consisting of multiple text file with different sizes. Evaluation has been performed using encryption time, decryption time and secrecy measure. Results showed that the proposed method has the ability to fulfil both efficiency and security factors with highest secrecy value. The impact of combination layer of encryption algorithms provides a higher secrecy value compared to single layer encryption. Keywords- cloud computing; AES; RSA; ECC; secrecy

At present, cloud computing is the fastest growing technology in today's world. Cloud computing is a model that provides the services based on as-needed and when-needed basis. Cloud computing provides online information storage, infrastructure and application. Many organizations shift towards cloud computing due to its benefits of less hardware maintenance and reduced expenditure start-up cost and at the same time, cloud computing offers many hazards. Network and Internet applications are growing very fast, since the need to secure these applications are very fast. For this purpose cryptography algorithms (symmetric & Asymmetric) are proposed. The use of relevant algorithm deals with the level of data safety in cloud because data security in cloud computing is a serious issue as the data centers are located worldwide. Authentication is the most essential procedure to ensure the cloud data in a secured manner. However, strong user authentication is the main requirement for cloud computing that reduces the unauthorized user access of data on cloud. Data security is a more important issue of cloud computing. Thus, the need to ensure the safety of information. Here in this survey paper, I have presented encryption based security algorithms for cloud computing.

In Cloud computing, Data sharing is the important functionality. Secure distributed data storage was developed to reduce the burden of data owner from managing numerous files, by transferring the files from data owner to proxy servers. Proxy servers can convert encrypted files for the owner to encrypted files for the receiver withoutthe necessity of knowing the content of the original files. In practice, the original files will be removed by the owner for the sake of space efficiency. Therefore, there is no guarantee that the outsourced files are not accessed by the unauthorized users and not modified by proxy servers is an important problem that has been considered. Hence, the issues on confidentiality and integrity of the outsourced data must be addressed carefully. In this paper, there are two Identity-Based Secure Distributed Data Storage (IBSDDS) schemes. The properties of IBSDDS schemes are as follows: The file owner can decide the access permission independently without the help of the private key generator; for one query, a receiver can only access one file, instead of all files of the owner. These schemes are secure against the collusion attacks, namely even if the receiver can compromise the proxy server, but cannot obtain the owner’s secret key. Though the first scheme is only secure against the chosen plaintext attacks (CPA), the second scheme is secure against the chosen cipher text attacks (CCA). To the best of our knowledge, it is the firstscheme where access permission is made by the owner for an exact file and collusion attacks can be protected.

Cloud Computing is an emerging technology widely used in the IT sector due its wide range of characteristics. These characteristics serve a medium for the intruders to attack the cloud and its users. The security of cloud can be compromised by employing different strategies and techniques. Many systems and techniques have been proposed for solving the security issues and implementing a high level of security on both the sides. Encryption is one of the best method suggested for making the cloud more secure and increasing its areas of application. This paper contains an overall study and comparison of various cryptographic algorithms implemented for cloud security. We also study some hybrid systems designed using combination of various crypto terminologies for enhancing data security in cloud. The hybrid systems implement multiple cryptographic algorithms like RSA and Digital signature, Diffie Hellman and AES in combination with Digital signature. Some of the comparison parameters included are technique proposed, type of algorithm, algorithm, scalability.
