Abstract
A method, system and computer program product for ensuring PKI key pairs are operatively installed within a secure domain of a security token prior to generating a digital certificate. The public key component of the PKI key pair is incorporated into a digital certificate which is returned to the security token for storage. The arrangement included herein incorporates the use of a critical security parameter to ensure a chain of trust with an issuing entity such as a registration authority. Furthermore, the arrangement does not require security officer or system administrator oversight during digital certificate generation as the critical security parameter provides a sufficient level of trust to ensure that digital certificate generation is being performed in conjunction with a designated security token rather than a rogue application. Lastly, separate inventive embodiments allow alternate communications and verification arrangements to be implemented.
