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.

Excerpt from the Book
2.4 Trusted Cloud Computing with Cryptographic Technique
Need of Trusted Computing, problems of widely used security applications is to protect the hardware platform against attacks on its integrity or modification of the security software. Within the PC area typical incidents and attacks are well known and are endangering PCs for home banking, but also on servers within companies and some other organizations which are used for very sensible and important data, like personal, e-commerce and billing few others. In embedded systems such incidents happen. examples are illegal changes or manipulations of data in controllers within automotive systems, e.g. odometer values for increasing the car value or vehicle theft protection systems but also other embedded system which handle goods of value.
Current approaches for solving this problem purely at the software level are by their very principle unpromising. As has since been amply confirmed from experience and security trends in the smart card world, a trusted and tamperproof security basis cannot be implemented using software-based solutions alone. This of course applies equally to host systems such as PC platforms as well as embedded controllers.
Trusted Computing Group, Major companies in the PC sector have therefore joined forces and worked to solve this problem with the aid of a new hardware approach and the creation of an associated industry standard. In 1999 Compaq, Hewlett-Packard, IBM, Intel and Microsoft established the Trusted Computing Platform Alliance; main aim was to create Trusted Clients. In order to make important applications like networks, communications and e-commerce more trustworthy. The emerging Trusted Computing Standard employs a secure hardware structure whose main component, the Trusted Platform Module (TPM), is specified as an LSI security chip.
