  • Patent number: 5894516
    Abstract: A method, apparatus, and article of manufacture for broadcasting encrypted software to a target computer enables simultaneous transmission to a plurality of licensed target computers. An encryption key is generated to encrypt a software package. The encryption key is then itself encrypted using a target computer identification code, and the encrypted encryption key is loaded onto the target computer. The encrypted software is broadcast, for example, via satellite, and received at the target computer. The target computer uses its identification code to decrypt the encrypted encryption key (i.e., unlock the encryption key). Once the target computer unlocks the encryption key, it uses the encryption key to decrypt the software to be installed on the target computer.
