Vishal Gohel proposes improving the security of virtual network communication and trusted launch of virtual machines in public infrastructure as a service (IAAS) environments. He plans to implement a secure runtime environment using the Xen hypervisor and demonstrate how it can enable secure remote computing services even under an untrusted management operating system. The expected outcomes are a secure network interface, comparison of different hypervisors for trusted virtual network communication, and the creation of a trusted computing environment for virtual machines requiring high security.
