Fast growing "Big Data" demands present new challenges to the traditional distributed storage system solutions. In order to support cloud-scale data centers, new types of distributed storage systems are emerging. They are designed to scale to thousands of nodes, maintain petabytes of data and be highly reliable. The support for virtual machines is also becoming essential as it is one of...
Hot/cold data separation in flash-based solid state drives has been considered important to the overall performance due to the costly garbage collection overhead. This work proposes a method that accurately and naturally identifies and separates hot/cold data while only incurs minimal overhead. The proposed method only requires minimal on-device RAM space. Simulation results have shown that the proposed...
Along with the development of cloud computing, cloud-based RFID is receiving more and more attentions of researchers and engineers. However, there is no research in which cloud computing is applied to RFID authentication schemes. Most current works lay emphasis on functionalities, lacking considerations about security and privacy. Classical RFID authentication schemes fail to meet the special security...
This paper mainly discusses the simulation aspect of online payment in e-commerce teaching by means of the cloud and virtualization technologies. The various transaction entities in online payment are simulated so that students and teachers access the simulation programs for virtual trading entity through the online or wireless means under cloud architecture. Students are able to fully experience...
Cloud Computing is becoming a well-known buzzword nowadays. Many companies, such as Amazon, Google, Microsoft and so on, accelerate their paces in developing Cloud Computing systems and enhancing their services to provide for a larger amount of users. However, security and privacy issues present a strong barrier for users to adapt into Cloud Computing systems. In this paper, we investigate several...
