Analyzing Privacy Issues in Cloud Computing Using Trust Model

2015

Cloud computing has become the burning research topic in the present as it seems to fulfill the current business needs by making the resources of hardware, software, platform and infrastructure available to the consumers as per their requirement and demands whenever and wherever they want. This leads to a lot of implementation challenges that come across, of which the most eminent are trust and security. This paper tries to find out the trust elements which could promote the use of cloud computing among users at large. An attempt is being made to find out the existing trust models and their drawbacks so as to lead to new trust models in the near future to bring more confidence in the use of cloud computing. KEYWORDSTrust, Trust Issues, Trust Models, User Behavior Based Trust Models.

Nowadays number of people who outsource their data to the cloud has been increased dramatically. Cloud computing offers cost-effective dynamic, scalable and shared services for enterprises from remote data centre. However, the problem of trusting cloud computing is a highest concern for most enterprises in such a way that trust is extensively in esteem as one of the highest barrier for the acceptance and expansion of cloud computing. So there is a need of trust model which help cloud consumers to find the provider that best satisfies their trust concerns in cloud computing by measuring the trustworthiness of cloud service providers.

Software as a service or (SaaS) is a new software development and deployment paradigm over the cloud and offers Information Technology services dynamically as "on-demand" basis over the internet. Trust is one of the fundamental security concepts on storing and delivering such services. In general, trust factors are integrated into such existent security frameworks in order to add a security level to entities collaborations through the trust relationship. However, deploying trust factor in the secured cloud environment are more complex engineering task due to the existence of heterogeneous types of service providers and consumers. In this paper, a formal trust management model has been introduced to manage the trust and its properties for SaaS in cloud computing environment. The model is capable to represent the direct trust, recommended trust, reputation etc. formally. For the analysis of the trust properties in the cloud environment, the proposed approach estimates the trust value and uncertainty of each peer by computing decay function, number of positive interactions, reputation factor and satisfaction level for the collected information.

Internet users are increasing at a logarithmic scale. Users are producing huge amount of data everyday across the world which is creating huge amount of data traffic. In this context data capturing , data analysis and the analysis sending it back to the stake holders is order of the day. In this scenario cloud plays an important role in big business. When cloud is playing an important role, users are using the cloud by generating data they are actually sending that data to the cloud. Here instantaneous information transformation from users to the cloud is one of the important component that is everyday happening today. Whatever data that is being produced should reside in the cloud. Whatever data which is available in the cloud should be available to the user back. This is the basic requirement as far as the users and maintainers of the cloud is concerned. In this context Trust plays an important role. In this paper we will address all the issues related to Trust, which are to be co...

Cloud computing is a model for enabling everywhere, suitable, on-demand network access. There are a number of challenges to provide cloud computing services and to accomplish this, it is necessary to establish trust across the cloud, between the user and the service provider. It is becoming increasingly complex for cloud users to make distinction among service providers offering similar kinds of services. There must be some mechanisms in the hands of users to determine trustworthiness of service providers so that they can select service providers with confidence and with some degree of assurance that service provider will not behave unpredictably or maliciously. An effective trust management system helps cloud service providers and consumers reap the benefits brought about by cloud computing technologies. Hence the objective of this chapter is to describe existing mechanisms that are used to determine a trust worthiness of a cloud service, various models that are used for calculatin...

Trust has been a hotspot for adopting cloud computing. This paper proposes a hybrid model to build, evaluate and expose trust. It uses different techniques like sliding window technique to reach optimum processes for trust value delivery. Trust value is evaluated through integrated mechanisms from literature. Moreover, measuring trust included evaluating SLA violations side to side with consumer customized measures for validating trust. Caching module has been added to ensure optimization of querying trusted services. Moreover, service registry and novel personalized modules have been added for tracking both cloud providers and cloud consumers behaviors. Furthermore, a comparison between literature's trust models and proposed model has been presented. It discusses criterion for building and evaluating trust. Finally, security analysis is presented to substitute different techniques against known security attacks.

Cloud computing is the most discussed research area now-a-days which helps to provide elasticity and flexibility in using the computing resources and services to fulfill the requirement of current businesses. Besides many advantages offered by cloud computing, it deals with many obstacles in the path of its growth, that are security issues, data privacy issues and distrust on cloud service providers (CSP). Trust is found to be an essential element for achieving security and confidence in the use of distributed computing. Various issues like data control, ownership, data integrity and security can be considered as important parameters of trust. This paper addresses the existing trust models for trust establishment in cloud services and also tries to find out the shortcomings of these models.

Cloud computing is a technology that promises resilient and flexible computing resources to the growing business. Along with many benefits of Cloud computing, there are various complex problems such as security and privacy of data that exists on Cloud. Trust is one of the key obstacles in the adoption of Cloud by the growing market due to absence of any reliable and efficient trust evaluation mechanism. It is difficult task for Cloud consumers to choose trustworthy provider among various service providers who provide similar type of services. There is a need to have-proper techniques/methods to establish trust; proper trust based models to evaluate the trust; and awareness of various possible attacks to know the robustness of the models. Hence this paper discusses existing state of the art trust management techniques, models and attacks, to help research community interested in designing trust based schemes in Cloud environment.

There is a big race for processing technology and storage and resource sharing capacity on interconnected servers around the world. This race defines what we call ―Cloud Computing‖. In recent years, cloud computing has developed rapidly in the context of the rise of the global Internet, and more and more services and products based on cloud computing have become more and more. As an emerging information service model, cloud computing has brought about tremendous and profound changes for computing services in the Internet era. However, due to the dynamic and complex nature of the cloud environment, users are faced with various data security and personal privacy risks when using cloud services. These problems have become an important factor hindering the development of cloud computing. In this context, Trust plays a crucial role in cloud environment to offer reliable services to the cloud customers. It is the main reason for the popularity of services among the cloud consumers. To ach...
