It is an open standard for authorization and gives a process for third-party applications to obtain users’ resources on the resource servers without sharing their login credentials. Popular social networks, such as Facebook, Google and Twitter make their APIs based on the OAuth protocol to increase user experience of Single Sign-On (SSO) and social sharing.
The OAuth 2.0 is an authorization protocol gives authorization on the Web. The result shows that ULTE has provided excellent performance than other algorithms. Simulation result represents the whole statistical distribution as stated in the algorithm. In this paper, we focus on simulation result and compare each algorithm with the proposed algorithm ULTE. We proposed an algorithm by which we can generate Salt by using the client’s real-time environmental information known as Location Information of user, User Time Information with Entropy Data at key generation time. We have to take inputs from beyond expected sources.

But to create powerful keys, we must avoid pseudorandom generators for making salt because hackers can easily crack the key by using it. By analyzing, we found that unique and random Salt plays a vital role for generating keys. Most of them use the PBKDF (Password-Based Key Derivation Function) and Salt for generating encryption keys. Every mechanism has its own security scheme. To avoid security problems, every cloud storage provider requires help from several security mechanisms. In modern life, users use the cloud spaces for storing important data and valuable information. After analyzing and comparing the performances, we have found SafeBox as the best client side encryption tool. For performance measuring, we have calculated the upload time including both encryption and synchronization time for different sizes of data files for each tool. To find out the best tool, we have analyzed the performance of the selected tools namely AxCrypt, nCrypted Cloud, SafeBox, SpiderOak, Viivo. " Which one provides more security among those tools? Which one consumes less time? In a single word, which one is the most effective? " These are the open questions to the users, in present days. It's very important for users to know that which tool is the best for encrypting and storing data in the cloud. Client side encryption tools are becoming popular in the field of cloud computing every day. For ensuring data security several client side encryption tools have been developed and widely used with their own features and security schemes. Cloud service providers maintain authentication and authorization mechanism but there are no mechanisms for data security if the users' credentials are compromised. To access data globally and timely we are storing data into Cloud Storage Space. We are using information and program extensively day by day. Simulation result shows the whole processes of Salt generation according to the ULTE Salt Generation Algorithm.Įverything of our life is migrating into virtualization and we are depending on information technology. Therefore, a new random number generate algorithm (ULTE) for Salt generation which is based on users' Location Information, Time Information, and Entropy Data (bit strings of s ystem noise sources like thermal noise or HDD s eek time) is proposed. Through analysis, we found that: generation of Salt by using any Pseudo random number generation algorithms could lead the i ntruders like hackers to c rack the encryption keys for multiple files stored in CSPs.

CSET encrypts each data file of client's with encryption key which are derived by a specialized algorithm called Password Based Key Derivation Function (PBKDF), and Salt, a random value plays vital role for making each encryption key unique and different from other keys. Client Side Encryption Tool (CSET) is used widely with their own features and security schemes to overcome the security problems in CSPs. If the us ers' credentials are compromised then information could be misused, or stolen. Cloud service providers (CSPs) maintain authentication and authorization mechanism but there are no mechanisms for data security. For accessing data globally and timely people are storing data, information, and programs into Cloud Storage Space.
Virtualization is the biggest issue in our modern life with information technology.
