ABSTRACT:
In one embodiment, a method is described to secure transfer data from one location to another for storage in an electronic component. The transfer occurs with part of the data routed to a first destination and the remaining data routed to a second destination. The data routed to the first destination is for securely loading a current sort encrypted key (SEK) and a next SEK into memory of the electronic component. The data routed to the second destination includes a private key which is recovered using the current SEK and the next SEK.
