From its start using supercomputers, scientific computing constantly evolved to the next levels such as cluster computing, meta-computing, or computational Grids. Today, Cloud Computing is emerging as the paradigm for the next generation of large-scale scientific computing, eliminating the need of hosting expensive computing hardware. Scientists still have their Grid environments in place and can...
The use of user specific virtual machines (VMs) in Grid and Cloud computing reduces the administration overhead associated with manually installing required software for every user on every computational resource. However, a large number of user specific VMs increases the risk of security attacks. In particular, Cloud computing providers like Amazon suffer from these problems, since they offer different...
Virtualization is a new area for research in recent years, and virtualization technology can bring convenience to the management of computing resources. Together with the development of the network and the network computing, it gives the virtualization technology more scenarios. The cloud computing technology uses the virtualization technology as while. With the development of the technology, it meets...
Static analysis is one of the most popular approaches of software analysis. As more and more software protects their code by transformation or encryption, then releases them at runtime dynamically, it is hard to statically analyze these protected executables because of the failure of disassembling. In this paper, we propose a novel and general technique to reconstruct binary files for static analysis...
As the continuous employment of the state-of-the-art technology such as polymorphism, metamorphism used by malware to avoid the anti-virus detection systems, virtual machine which forces malware converting into its original form by executing it in a virtual environment has played an increasingly important role in malware detection system. In this paper, we introduce all types of virtual machines and...
Many software systems in use today have enormous trusted computing bases (TCBs). We propose an architecture that makes it possible to shrink the TCB of many such systems. Our solution is based on a virtual-machine (VM) with added information-flow capabilities. In our architecture, all application programs run outside of the TCB under the control of the VM and cannot cause information leaks even if...
Biologists have long recognized the dangers of the lack of diversity or monocultures in biological systems. Recently, it has been noted that much of the fragility of our networked computing systems can be attributed to the lack of diversity or monoculture of our software systems. The problem is severe. Because it is virtually inevitable that software will ship with flaws, our software monoculture...
