With the rapid development and popularity of cloud computing technology, more and more Collaborative Virtual Environment (CVE) systems are migrated to cloud computing environment to improve the effectiveness of resource usage. Virtual Machine (VM) placement in cloud data center is a key issue of providing high-efficient cloud platform for CVE system. However, most existing VM placement algorithms...
With the explosion of data in the past decade, big data is becoming a research hotspot in the information field. Many cloud-based distributed data processing platforms have been proposed to provide efficient and cost effective solutions for big data query processing, such as Hadoop, Hive, Pig, etc. However, most of the current research works are focus on improving the performance of query processing...
SMS4 is the first national standard of cryptographic algorithm in China. It is a block cipher with 128 bits key. Because SMS4 is a relatively new algorithm, there are no hardware accelerators specific to it and no proposal to implement it on smart cards until now. In this paper, SMS4 was designed and implemented on smart cards. At first, the optimized implementation algorithm of SMS4 was given so...
