Remote server vulnerability exploit is one of the most troublesome threat to the Internet security. An effective defense against the remote vulnerability exploit is code randomization, which randomizes the program code address to disrupt the malicious payload execution. Unfortunately, code randomization is particularly susceptible to address exposure vulnerabilities; the leak of a single code or data...
Software memory disclosure attacks, such as buffer over-read, often work quietly and may cause leakage of secrets. The well-known OpenSSL Heartbleed vulnerability leaked out millions of servers' private keys, and caused most of Internet services insecure during that time. Existing solutions are either hard to apply to large code bases, or too heavyweight (e.g. by involving a hypervisor software or...
Commodity operating systems have already gained functionality of virtual machine monitor. Nested virtualization is needed to run these commodity operating systems as virtual machines. Furthermore, with nested virtualization technology, users can run a self-configured virtual machine monitor (VMM) in Infrastructure as a Service (IaaS) cloud computing model, and live migration of VMM can be realized...
Partially linear models are extended linear models where one covariate is nonparametric, which is a good balance between flexibility and parsimony. The partially linear stochastic model with heteroscedastic errors is considered, where the nonparametric part can act as a trend. The estimators of the parametric component, the nonparametric component and the volatility function are proposed. Furthermore,...
The use of virtualization in cloud computing is becoming more and more popular. Cloud service providers leverage virtualization technology to multiplex hardware resource, consolidate servers, and provide a rounded executing environment to remote cloud users. However, the current executing environment the cloud provides is not trustable. For a user's computing environment faces threats from other malicious...
