Abstract
A form of removable memory, such as a universal serial bus (USB) flash device, may enable a subscription-based computing system from any PC. The device may include an execution unit including a processor, a private memory including an encrypted application, a computing system interface, a cryptographic unit including a secure storage with a number of metering units, and a computer-readable medium. The computer-readable medium may include instructions for routing messages and data from the execution unit through the computing system interface to a connected computing system. Further, encrypted application data may be routed through the cryptographic unit to the execution unit to thereby transform the encrypted application into executable data for use by the computing system. Also, the device may decrement a number of metering units stored at the device during execution of the encrypted application by the computer.
