A secure end-to-end communications system provides end users access to vault-based custom applications of an organization for purposes of conducting electronic commerce. The system includes a web-based vault controller running an application, e.g. a registrations application in a vault cryptographically linked to a database and a Certificate Management System (CMS) for generating digital certificates, and at least one remote vault agent coupled to the vault controller for providing vault-based custom applications to end users. An X.500 directory is coupled to the CMS and cryptographically linked to the remote vault agents for storing end user data. The remote vault agent is an application which comprises a collection of Application Programming Interfaces (APIs) which provide a secure interface to the vault controller; a Lightweight Data Access Protocol (LDAP) used to access the X.500 directory; a secure depositor coupled to vault-based custom applications of an organization. The secure depositor includes APIs to perform cryptographic functions in passing communications between vaults used by the vault agent and vaults used by the vault controller or vaults used by other vault agent applications and a secure depositor library which uses functions in the LDAP to access the X.500 directory. The remote vault agent accesses the web based vault controller on a non-web basis to enable remote custom applications to communicate securely with vault-based applications, such as a registration application that administers digital certificates.

Secure communication system and method of operation for conducting electronic commerce using remote vault agents interacting with a vault controller

A secure-end-to-end communication system for electronic business system and method of operation, e.g., the Internet, includes a web server&mdash;vault controller having personal storage vaults in the controller for users, registration and certification authorities. Each personal vault runs programs on the controller under a unique UNIX user ID. Data storage is provided by the controller wherein the storage is owned by the same user ID assigned to the vault. A registration authority running as a software application in the controller processes requests to issue, renew and revoke digital certificates issued by a certification authority using two pairs of public-private keys. The registration authority interacts with the vault controller to decide whether an applicant qualifies to receive a digital certificate. The certification authority running as software application in the controller includes a certificate management system that provides services such as issuing, revoking, suspending, resuming, and renewing a user's right to digital certificates.
