Abstract
A method of authorizing transfer of software into an embedded system, comprising the steps of obtaining a hardware identification code (HWID) relating to one of a service/recalibration tool and an embedded system, obtaining a software identification code (SWID) relating to at least a portion of software information that is not resident in the embedded system but is to be downloaded into the embedded system, creating a password as a function of the HWID and the SWID, and downloading a password-protected portion of the software information from the service/recalibration tool into the embedded system based on the password.
