  • Publication number: 20260205269
    Abstract: Provided are systems and methods for managing access to encrypted data used by applications. The system includes a processor configured with program code stored in memory for a key management engine and a cryptographic tracking engine. The cryptographic tracking engine will cause the processor to generate a tracking token for a data payload with a cryptographic key identifier and a data context policy reference; store the tracking token in a tracking token database; receive a request from the key management engine to encrypt the data payload based on a request from a first application servicer; and permit the key management engine to encrypt the data payload for the first application servicer based on determining that the first application servicer fulfills the data context policy. The key management engine will cause the processor to encrypt the data payload based on a response from the cryptographic tracking engine.

  • Patent number: 5553144
    Abstract: A method and system are disclosed for selectively altering the functional characteristics of a data processing system without physical or mechanical manipulation. A data processing system is first manufactured having a predetermined set of functional characteristics. A multibit alterable code which includes a functional characteristic definition is then initially loaded into physically secure, nonvolatile memory within the data processing system, utilizing an existing bus, or a fusible link which may be opened after loading is complete. The functional characteristic definition is loaded from nonvolatile memory into a nonscannable register within a secure portion of a control logic circuit each time power is applied to the data processing system and the definition is then utilized to enable only selected functional characteristics.

  • Patent number: 5365587
    Abstract: A system is disclosed for selectively altering the functional characteristics of a data processing system without physical or mechanical manipulation by providing an access code from a remote personal identification number generator to a secure controller and store of the computer system. This enables remote authorization of change in function of the computer system, such as performance tune up, speeding clock time, changing function and like changes. The computer system is first manufactured having a predetermined set of functional characteristics. A multibit alterable code which includes a functional characteristic definition is then initially loaded into physically secure, nonvolatile memory within the data processing system, utilizing an existing bus, or a fusible link which may be opened after loading is complete.
