Abstract
A system for certifying authorizations includes an authorizing computer and an authorized computer interconnected by a computer network. The authorizing computer creates a public key pair comprising a new public key and a new private key, and creates an authorization certificate that certifies that a holder of the authorization certificate is authorized to perform an action referred to in the authorization certificate. The authorization certificate includes the new public key. The authorizing computer causes the authorization certificate and the new private key to be transmitted to the authorized computer. The authorized computer receives the authorization certificate and the new private key and decrypts messages using the new private key as evidence that the authorized computer has obtained the authorization certificate legitimately.
