Digital certificate proxy |
摘要 |
The invention generates a temporary digital certificate with a useful life of only a few minutes to a few hours. An expiration time is attached to such temporary digital certificate by a secure computer platform that is presented with a user's smart-card. Expiration dates one or two years after the issuance of the smart-card are conventional. A digital certificate issued by a central authority is carried within the smart card and is used by the secure computer platform to generate temporary digital certificate. The temporary digital certificate functions as a proxy digital certificate that will allow the user to immediately pocket the smart card and thus avoid the possibility of forgetting it in a card reader.
