Abstract: According to one embodiment, a method comprises executing an untrusted host virtual machine monitor (VMM) to manage execution of at least one guest virtual machine (VM). The VMM receives an encrypted key domain key, an encrypted guest code image, and an encrypted guest control structure. The VM also issues a create command. In response, a processor creates a first key domain comprising a region of memory to be encrypted by a key domain key. The encrypted key domain key is decrypted to produce the key domain key, which is inaccessible to the VMM. The VMM issues a launch command. In response, a first guest VM is launched within the first key domain. In response to a second launch command, a second guest VM is launched within the first key domain. The second guest VM provides an agent to act on behalf of the VMM. Other embodiments are described and claimed.

Abstract: A helmet includes a shell having an interior surface, a padding disposed along the interior surface of the shell, and a chinbar. The padding defines a first engagement surface positioned at a first lateral side of the padding and a second engagement surface positioned at an opposing second lateral side of the padding. The chinbar includes a cage, a first flange, and a second flange. The cage includes a first end defining a third engagement surface and a second end defining a fourth engagement surface. The third engagement surface interfaces with the first engagement surface and the fourth engagement surface interfaces with the second engagement surface. The first flange extends from the first end of the cage. The second flange extends from the second end of the cage. The first flange and the second flange of the chinbar are embedded within the padding.
