摘要
Authentication of an upgrade to computer readable program code of a target embedded device is accomplished by causing the computer processor of the embedded device to access an unique machine identifier; to access an identifier key associated with the upgrade; to process the identifier key and/or unique machine identifier, such as by decrypting the key and/or encrypting the identifier; to compare the identifier key with the unique machine identifier; and causing the computer processor, if the identifier key matches the unique machine identifier, to enable the upgrade; else, to fail the upgrade.
