We have been assigned the task to prove the security of virtualization environment provided by xen.We request your assistance in this regards and clarify the following issues. Does Xen follow any security model, in particular, does a Random Oracle (RO) fit in Xen? When there are concurrent Guest OS running on the same hardware, then there has to be a mechanism for concurrency control and fairness, how does Xen implement these? Shared memory access has to make sure that one "malicious" OS doesn't access other's memory, where and how is this done? Similarly with shared network, how and where is security handled in this case so that packets meant for one OS are not accessible to other OS? Does xen has cryptography implementation in the code ? If you have idea regarding *"provable security" *property of Xen , can you give us a gist of it ?
