Abstract
A system and method for securely distributing PKI data, such as one or more private keys or other confidential digital information, from a PKI data generation facility to a product in a product personalization facility that is not connected to the PKI data generation facility and is assumed to be a non-secure product personalization facility. The system includes a PKI data loader for securely transmitting the encrypted PKI data transferred from the PKI data generator to a PKI server at the product personalization facility. The PKI server then transfers the PKI data to the product of interest, typically via a PKI station acting as a proxy between the PKI server and the product. In each communication step, PKI data being transferred is encrypted multiple times and the system is designed such that if any intermediate node is compromised with all of its keys, the overall system has not yet been compromised.
