Abstract
System and methods for facilitating electronic commerce by securely providing certificate-related and other services, including certificate validation and warranty services. The system services include a certificate status check service and a warranty service. The certificate status check service allows a relying customer to validate a subscribing customer's digital certificate. The warranty service allows the relying customer to receive a collateral-backed warranty that the subscribing customer's digital certificate is valid, and also confirms the ability of the subscribing customer to pay. All participants and a root entity are provided with a transaction coordinator for combining services and operations into a single transaction having the qualities of atomicity, consistency, isolation, and durability. The transaction coordinator provides a single consistent interface for certificate-status messages and requests, as well as messages and requests relating to other services.
