Abstract

A system installs and enables the use of a temporary certificate at a remote site. The system comprises a global server site, a temporary client site and a web site. The global server site includes a security module that identifies and authenticates the user at the temporary client site, and a web server engine that downloads a key generation downloadable and a certificate request engine downloadable upon user authentication to the client site. The client site includes a web engine that executes the key generation downloadable to generate a public key and a private key, and executes the certificate request engine downloadable to send the a temporary certificate request (including the public key) to the global server site. A temporary certificate generator at the global server site generates a temporary certificate having the public key and a validity period. The web server on the global server site sends the temporary certificate and a certificate installation downloadable to the web engine on the client site, which executes the downloadable thereby installing the temporary certificate. The web server on the global server site can also send a certificate maintenance downloadable and a certificate de-installation downloadable to the client site. The web server engine maintains a revocation list that contains information identifying revoked temporary certificates, so that a revoked but thusfar unexpired certificate cannot be improperly used. The web site reviews the temporary certificate for authenticity and contacts the global server site to review the revocation list and determine whether the temporary certificate has been revoked.
