With the rapid development of network technology and the increasingly complexity of system function, the embedded system is facing more and more serious threats. Previous researches on kernel monitoring and protection widely relies on higher privileged system components, such as hardware virtualization extensions, to isolate security tools from potential kernel attacks. These approaches increase both...
Recent technological advances have accelerated the design and worldwide deployment of mobile payment systems (m-payment). However, m-payment over open devices and networks poses security challenges of a new dimension that users disclose lots of sensitive information and privacy can't be protected properly in open environment. In this paper, we propose a mobile payment architecture employing with trusted...
Recent technological advances have accelerated the design and deployment of kinds of secure applications on smartphones. Although users can access and handle their data flexibly and stably with mobile devices, not only computing devices, it poses security challenges of a new dimension that users disclose lots of sensitive data and privacy information over open devices and networks as well. Thus, more...
The importance of storing and processing data eficiently is intensively highlighted in modern information technology infrastructures. Hadoop Distributed File System (HDFS) acts as the primary storage in modern cloud service environments and has been widely adopted for its portability and fault-tolerance. Current deployment of HDFS which runs on top of commodity hardware is unable to deliver desirable...
As PC clusters increase in popularity and quantity, message-passing between nodes has been an important issue for high failure rate in the network. File access in a cluster file system often contains several sub-operations, each includes one or more network transmissions. Any network failures will cause the file system service unavailable. In this paper, we describe a highly reliable message-passing...
Virtual machine technology can provide high server utilization and service consolidation on an individual physical machine, and gains acceptance in diverse fields. In a growing number of contexts, many situations require high-performance network virtualization. Paravirtualized network system adopts split driver model, and uses dynamic shared memory mechanism for communication between unprivileged...
The overhead caused by virtualization makes it difficult to apply VM in the applications which require high degrees of both performance isolation and efficiency, such as the high performance computing. In this paper, we present a lightweight virtual machine, named Solo. It simplifies the design of VMM greatly by making most privileged instructions bypass the VMM, except the I/O operations. Solo allows...
