ABSTRACT:
A method and apparatus that allows a computer system to trust both program and data files without the intervention of the user and without the possibility of circumventing the model of trust. A file system incorporates two levels of validation for programs and data. A first level of validation specifies sources that the user has decided are trustworthy or untrustworthy. A second level of validation specifies sources that the system itself considers trustworthy or untrustworthy. For data to be acceptable, it must be acceptable to both levels of checking. In addition, both the user and the system can specify multiple acceptable signatures and further allows various ones of the multiple signatures to have different levels of access to the system.
