ABSTRACT:
Software updates remedy vulnerabilities in a computer program that has been distributed and installed on a plurality of computers. The software updates are distributed in encrypted form, and then, after the encrypted update has been delivered to a sufficient number of machines, the decryption key for the update is delivered. Since the key is relatively small, it can be distributed to a large number of machines very quickly, thereby reducing the amount of time between when the update is first known to the public, and the time at which all or most machines have installed the update to protect against the vulnerability.
