摘要： Disclosed is a system for warranting the identity of a party over an electronic network. The system comprises a root entity (104) and a plurality of additional entities (106, 108, 110). Each additional entity is admitted to the system after agreeing to abide by a plurality of operating rules promulgated by the root entity. The additional entities may comprise level-one participants (106) and level-two participants (110). Certificate authorites maintained by the level-one participants issue digital certificates to their customers. The certificates bind the customers to their public keys. System customers are also provided with a warranty request formatter which is adapted to formulate a request for a warranty as to the veracity of information contained in a digital certificate. Warranty offers are issued by the participant that issued the digital certificate identified in the warranty request.

The seller is a customer of a second financial institution (104) or relying participant, which is a certificate authority and issues a hardware token including a private key and a signed digital certificate. The system also includes a root certificate authority that operates a certificate authority that issues digital certificates to the issuing and relying participants. Each participant and the root entity are preferably provided with a transaction coordinator that provides a single consistent interface for certificate-status messages and requests, as well as messages and requests relating to other services.
