Secure Communication Mechanism in Xen Hypervisor Tun, Thant Zin In virtualization architectures, a smalltrusted computing base (TCB) minimizes theattacks which could be dangerous the security ofthe entire system. The TCB for an applicationincludes the hardware, the virtual machinemonitor (VMM) and the whole managementoperating system (OS). The management OScontains not only the device drivers but alsovirtual machine (VM) management functionality.This management OS is not acceptable to trustfor many applications due to its high privilegelevel. In this paper, the secure virtual machineexecution mechanism under the assumption ofuntrusted management OS (Dom0 in Xen) isproposed. This mechanism provides theconfidentiality and integrity of the guest VM(DomUs in Xen). A secure communicationchannel is also proposed to exchange the secureinformation between Dom0 and the DomUs byauthenticating and avoiding replay attacks. 2012-02-28 http://hdl.handle.net/20.500.12678/0000004497 https://meral.edu.mm/records/4497
