Abstract

See full text

Enhanced multi-level cryptographic transformations that secure electronic files are disclosed. The secured electronic files contain not only secured data but also security information. The security information includes cryptographic structure information, access rules and secrets (e.g., keys). The cryptographic structure information explains the multi-level cryptographic transformations associated with securing or unsecuring the electronic files. The access rules and the secrets are used by the cryptographic transformations to secure the electronic files. Since the secured electronic files contain the cryptographic structure information, the particular cryptographic transformations (including their sequencing) can vary with each electronic file, if so desired. Typically, the secured electronic files are secured and managed by a file security system, such as a distributed security system.
