Abstract: Cloud computing has been intended as the next age group architecture of IT Enterprise. In contrast to traditional results, cloud computing moves the application of software and databases to large data centers, where the organization of the data and services may not be fully truthful. So, this paper attentions the need for users to trust the commercial cloud provider’s and security issues of storing data in cloud storage service. The cloud storage is one of the projecting services presented in cloud computing. This is a implemented paper and proposes a method for cloud storage that allows user to store and access the data securely using SHA256 algorithm and implementing it in Amazon Web Services (AWS) Cloud. In this paper we have proposed a solution which uses a mechanism of hash function along with various cryptography tools to provide better security to the data stored on the cloud (AWS). Keywords: Integrity, Amazon Web Service (AWS), Cloud Computing, Storage, Security, SHA256 Algorithm.
1. INTRODUCTION The main call for cloud computing is that the user can only utilize what they required and the user’s only pay for what they use. One of the most important service offered by cloud is cloud storage, which refers to the online space where the user can store the data securely. Cloud computing will bring several advantages to the market and the three most important are security, effectiveness and scalability. Cloud storage is a service model in which data is preserved, managed and backed-up remotely and made accessible to user over a network. The biggest concern about cloud storage is security and which is considered as a key requirement of a cloud. The main risk in cloud is that there is no proper security inside the cloud and it’s fails to protect, the risks using cloud services that can lead to higher costs and mostly potential loss for business. Security of data remains a concern in computing and this problem arises from the fact of sensitive data. To overcome this, we have proposed a solution which generates a hash values using SHA256 algorithm which helps us to secure data in the cloud. SHA256 stands for Secure Hash Algorithm and this algorithm is used for cryptographic security and produce’s unique hash values and this algorithm mainly focuses on the speed of generating the key.
2. LITERATURE SURVEY Vaidehi M [1] They proposed a technique and algorithm used to ensure security, SHA256 has been applied. It handles 256 bits known as digest length. This does not use any keys. Secure hash algorithm is commonly used in data security for various applications and this convert actual data into encrypted form if the input data of hash changes then the output hash also changes. They have detailed about data distributed on three levels, that is network, host and application level. And also they mentioned it is important to satisfy the requirements which is related to security to store data, which includes integrity, availability and confidentiality.
