20090271877, Oct 29, 2009

Filed:

Mar 19, 2009

Appl. No.:

12/407537

Inventors:

Paul Bradley - Cumberland RI, US

International Classification:

G06F 7/04
G06F 11/00

US Classification:

726 33, 726 26, 726 34

Abstract:

Systems and methods for securing an embedded system are disclosed. An embedded system comprises a hardware subsystem including physical components of the embedded system, a software subsystem including a software application and a program code, and a programmable logic subsystem programmed to monitor one or more parts of the hardware and software subsystems and interactions thereof to detect tampering of the embedded system. The programmable logic subsystem is capable of being activated by a security function in the software subsystem or by a special hardware component in the hardware subsystem. The activation of the programmable logic subsystem facilitate a coupling of the hardware, software, and the programmable logic subsystems. The program code can be used to dynamically re-program the programmable logic subsystem.

Appl. No.:

12/903882

Inventors:

David J. WHELIHAN - Framingham MA, US
Paul BRADLEY - Cumberland RI, US

Assignee:

DAFCA, INC. - Framingham MA

International Classification:

G06F 21/22
G06F 1/24
G06F 9/24

US Classification:

726 22, 713100, 713 2

Abstract:

In exemplary embodiments, methods and apparatuses for securing electronic devices against tampering or unauthorized modifications are presented herein. One or more system locks may be installed in the system at a location between two or more subsystems along a communications path. Each system lock may be associated with a particular subsystem. The system locks may monitor the state of the system, including transactions targeting associated subsystems, and the transactions and/or state of the system may be compared to known valid transactions and states. If the requested transaction or enacted system state differs from a known acceptable transaction or state, a notification may be generated and countermeasures may be enacted. In some embodiments, the system locks may be located in a system bus on an electronic device to ensure that software executed on the electronic device remains free of tampering.

Appl. No.:

12/903965

Inventors:

David J. WHELIHAN - Framingham MA, US
Paul BRADLEY - Cumberland RI, US
Kumar DWARAKANATH - Framingham MA, US

International Classification:

G06F 12/14

US Classification:

713193, 713189

Abstract:

A method of designing an electronic system is provided to protect the electronic system from unauthorized access and hardware piracy. The method includes describing the electronic system in a first design and replacing a portion of the electronic system with a reconfigurable module to generate a second design. The reconfigurable module includes a reconfigurable logic block and a configuration block for storing configuration data. The method also includes encrypting configuration data and saving the encrypted configuration data separately from the reconfigurable module. The reconfigurable logic block is configured to correspond to the portion of the electronic system in the first design when the configuration data is loaded in the configuration block.
