Abstract:
1. A method comprising: connecting a portable device to a host device, wherein the portable device is configured to execute a process; establishing a communication link between the portable device and the host device; identifying the portable device to the host device; executing the process with a computing module of the portable device, the process configured to generate a computing environment; determining a first timing identifier; determining a second timing identifier associated with the process; enabling an application on the host device to interact with the process based, at least in part, on a protocol when the second timing identifier is valid relative to the first timing identifier, wherein enabling the application on the host device to interact with the process includes providing the computing environment to an application executing on the host device; and denying access to the process when the second timing identifier is invalid relative to the first timing identifier, wherein the second timing identifier is invalid when the second timing identifier represents a time that is after another time represented by the first timing identifier.
