Abstract

A system for open electronic commerce having a customer trusted agent securely communicating with a first money module, and a merchant trusted agent securely communicating with a second money module. Both trusted agents are capable of establishing a first cryptographically secure session, and both money modules are capable of establishing a second cryptographically secure session. The merchant trusted agent transfers electronic merchandise to the customer trusted agent, and the first money module transfers electronic money to the second money module. The money modules inform their trusted agents of the successful completion of payment, and the customer may use the purchased electronic merchandise. A certificate data signed by a trusted authority is stored in a tamper proof electronic processing device, which certificate includes a unique device ID and a public key of the device, in addition to device owner ID data. The processing device is programed to validate credential data received from other such processing devices.
