Document from the year 2013 in the subject Computer Science - Internet, New Technologies, grade: A, , language: English, abstract: This book focuses on the security issues in Cloud Computing System; Cloud Computing is an upcoming paradigm that offers tremendous advantages in economical aspects such as reduced time to market, flexible computing capabilities and limitless computing power. To use the full potential of the cloud computing, data is transferred, processed and stored by external cloud providers. However, data owners are very skeptical to place their data outside their own control sphere. This book discusses the security controls to protect data in cloud computing environment using Cryptographic technique. Cloud computing provide the way to share distributed resources and services that belong to different organizations. Since cloud computing share distributed resources via the network in the open environment, thus it makes security problems important for us to develop the cloud computing application. In this book, we pay attention to the security requirements in cloud computing environment. We proposed a method to build a trusted computing environment using cryptographic technique, for cloud computing system by integrating the trusted computing platform into cloud computing system. Security has become a major concern in cloud computing environment. Where the resources are shared by many. Users join and leave the cloud dynamically which leads to a serious challenge for the security of shared resources. Hence there¿s a need to establish trust in the cloud so that the users are ensured of their data security. We propose a model system in which cloud computing system is combined with trusted computing platform with trusted platform module. In this model, some important security services, including authentication, confidentiality, data Storage, data security and access control, are provided in cloud computing system.
