Abstract
Data, including a program and software updates, is encrypted by a public key encryption system using the private key of the data sender. The data is also digitally signed by the sender. The receiver decrypts the encrypted data, using the public key of the sender, and verifies the digital signature on the transmitted data. The program interacts with basic information stored within the confines of the receiver. As result of the interaction, the software updates are installed within the confines of the user, and the basic information stored within the confines of the user are changed.
