Abstract

The data processing system rotates as a whole, or all hardware parts to be protected are continuously or intermittently subjected to forms of acceleration other than rotation. If a circuit board rotation is stopped, or its acceleration changed by an unauthorised party, a spring presses a destruction tool directly onto the memory or processing chip etc. to destroy it. Various other claims are included.

Description

Zugriffsschutz für Software elektronischer Datenverarbeitungsanlagen und anderweitig realisierter Speichermedien über durch Fliehkraft direkt bewirkte oder indirekt durch Fliehkraft ausgelöste mechanische Zerstörung des Speichermediums.Access protection for software for electronic data processing systems and otherwise implemented storage media over directly caused by centrifugal force or indirectly through Centrifugal force causes mechanical destruction of the storage medium.

Software kann bisher kaum wirksam gegen Kopieren, gegen unerlaubte Mehrfachverwendung, gegen das Übernehmen von Programmteilen, gegen das Verwenden zugrundeliegender Algorithmen geschützt werden, etc.So far, software can hardly be effective against copying, against unauthorized multiple use, against taking over Program parts, against using underlying Algorithms are protected, etc.

Es wird daher hier in diesem Patent vorgeschlagen, die im Sinne eines wirksamen Schutzes relevanten Speicher- und/oder Verarbeitungsmedien oder auch die gesamte Datenverarbeitungsanlage einer bestimmten Beschleunigung (im einfachsten Fall einer durch Rotation bewirkten Fliehkraft) auszusetzen, bei deren Veränderung oder Unterbrechung Mechanismen in Gang gesetzt werden, die die für den Zugriffsschutz relevanten Teile direkt oder indirekt zerstören. Stellvertretend soll hier nur ein Beispiel eines Prinzipaufbaus beschrieben sein, das am einfachsten verständlich ist - die durch Rotation über zwei Achsen bewirkte Beschleunigung, die in ihrer Veränderung oder Unterbrechnung zum Auslöser für die mechanische Arbeit des Zerstörungswerkzeuges wird: Die Hardware wird auf zwei rotierenden Achsen zum Drehen gebracht. Auf der einen, von einem Motor gedrehten Achse ist wiederum ein Motor befestigt, der seinerseits eine weitere Achse dreht. An der Achse des zweiten Motors ist schließlich die Platine befestigt. Auf der Platine sind direkt über den betreffenden Schaltkreischips für jede Drehbeschleunigung getrennt sensitiv und damit zweifach auslösbare Zerstörungswerkzeuge angebracht, die bei Veränderung oder Unterbrechung der Rotation direkt auf das Chip drücken und dieses damit zerstören. (Falls für Chips bestimmte Umgebungen z. B. Schutzgas, Abschirmung, etc. vorgesehen sind, sind diese Umgebungen so zu realisieren, daß sie ggf. auch leicht zerstörbar sind: z. B. Schutzgas unter leicht zerstörbarer Abdeckschicht, -folie, etc.; z. B. Abschirmung unter dünner, leicht zerstörbarer Metallfolie; etc.). Die Zerstörung kann direkt oder indirekt von der Veränderung oder Unterbrechung der Rotation verursacht oder ausgelöst werden.It is therefore proposed here in this patent, which in For effective protection relevant storage and / or Processing media or the entire data processing system a certain acceleration (in the simplest A centrifugal force caused by rotation), mechanisms for changing or interrupting them be set in motion for access protection destroy relevant parts directly or indirectly. Here is just one example of a basic structure be described, the easiest to understand is - the acceleration caused by rotation over two axes, those in their change or interruption to trigger the mechanical work of the destruction tool will: The hardware will be rotating on two Axes made to rotate. On the one hand, by an engine rotated axis is in turn attached to a motor, which in turn another axis rotates. On the axis of the second Motors is finally attached to the board. On the Circuit boards are directly over the relevant circuit chips for each spin separately sensitive and therefore twice triggerable destruction tools attached, the if the rotation is changed or interrupted directly press on the chip and destroy it. (If environments intended for chips e.g. B. shielding gas, shielding, etc. are provided, these environments are so too realize that they can also be easily destroyed: e.g. B. protective gas under easily destructible cover layer, -foil, etc .; e.g. B. Shielding under thin, easily destructible Metal foil; Etc.). The destruction can be direct or indirectly from changing or interrupting the Rotation is caused or triggered.

Claims

1. The data processing system rotates as a whole or in the hardware parts relevant for access protection together with the mechanical destruction device and / or the relevant parts become one (persistent or intermittent) other form of acceleration (not only Rotation) exposed.

2. Will the rotating hardware board or an equivalent Data processing unit unauthorized in their Rotation (or other type of acceleration) stopped (or the acceleration changes), e.g. B. a spring a destructive tool directly on the relevant one Part of the storage and / or processing medium (e.g. circuit chip, magnetic memory, miniature tube constellation, laser-optical crystal (memory), etc.) and destroys it. The destruction tools can be completely different in their execution, d. H. destroy directly in another way (e.g. chemical, magnetic, laser-optical, optical, etc.), they become but all by stopping / changing the rotation or changing another accelerated motion or sequence of movements triggered, controlled etc.

3. Or by stopping or changing a centrifugal switch, Centrifugal release, acceleration sensor or similar brought up, which is only an electromagnetic, triggers chemical, etc. working tool (indirectly), that the relevant part of the memory and / or Processing medium destroyed.

4. Several u. U. rotating combined Axes (or otherwise accelerated and interconnected Parts) and several (and / or combined) (Destruction) tools can be used at the same time.

5. An energy source attached to the rotated etc. unit does that u. U. Energy supply dependent (destruction) tool independent from the outside and unassailable. The energy source can further, with the destruction not necessary directly related or also relevant to destruction Provide processes independently from outside with energy (e.g. supplying the operation of the rotations with Energy from inside the device, e.g. B. Supply a test facility with energy, which after Destruction checks to see if the destruction is complete or sufficient according to the respective needs was enough, and possibly the energetic supply of the in the event of non-destruction, further to be initiated below Steps, etc.).

6. Through the after the production of the (possibly already with software loaded) hardware to start rotation (or other Acceleration) the tools (e.g. by pulling a lock away from the rotation, etc.) can be "armed" without outside an intervention becomes necessary.
