ABSTRACT:
A cryptographic system with key escrow feature that uses a method for verifiably splitting user's private encryption keys into components and for sending those components to trusted agents chosen by the particular users is provided. The system uses public key certificate management, enforced by a chip device that also self-certifies. The methods for key escrow and receiving an escrow certificate are applied to register a trusted device with a trusted third party and to receive authorization from that party enabling the device to communicate with other trusted devices. The methods for key escrow also provide assurance that a trusted device will engage in electronic transactions in accordance with predetermined rules.
