Cloud Computing

Cuvinte cheie: cloud computing, security, privacy, integrity

The cloud computing is a new computing model which comes from grid computing, distributed computing, parallel computing, virtualization technology, utility computing and other computer technologies and it has more advantage characters such as large scale computation and data storage, virtualization, high expansibility, high reliability and low price service. The security problem of cloud computing is very important and it can prevent the rapid development of cloud computing. This paper introduces some cloud computing systems and analyzes cloud computing security problem and its strategy according to the cloud computing concepts and characters. The data privacy and service availability in cloud computing are the key security problem. Single security method cannot solve the cloud computing security problem and many traditional and new technologies and strategies must be used together for protecting the total cloud computing system.The proliferation of mobile devices, coupled by the increase in their capabilities, have enabled the establishment of a rich mobile computing platform that can be utilized in conjunction with cloud services. In this chapter, we overview the latest mobile computing models and architectures focusing on their security properties. In particular, we study a wide range of threats against the availability, privacy and integrity of mobile cloud computing architectures in which the mobile devices and the cloud jointly perform computation. We then present defense mechanisms that ensure the security of mobile cloud computing architectures and their applications. Throughout the chapter, we identify potential threats as well as possible opportunities for defenses.
