Abstract
A pay-per-use or pay-as-you-go computer uses a secure memory to store individual unique program identifiers. Each unique program identifier is associated with a particular hardware or software component, or service, or the entire computer available to a user. By combining the unique program identifier with a computer hardware identifier uniquely identified transactions may be tracked for both billing and reconciliation. Certificates associated with each unique program identifier, and coupled to the hardware identifier, provide a cryptographic basis for mutual verification of messages, requests, configuration instructions, and provisioning.
