Single-chip system, method for operating a single-chip system, and motor vehicle

Abstract

Single-chip system, having multiple computing units, in particular computer cores and/or CPUs, at least one input/output unit, a memory unit, and an input/output control unit that coordinates the communication between the computing units and the at least one input/output unit, wherein the single-chip system further has an attack detection unit, produced as hardware, that is connected by means of a hardware signal connection to at least the input/output control unit as a component of the single-chip system and evaluates input signals received from the input/output control unit for a rule infringement in a set of attack detection rules, which rule infringement needs to be logged and/or responded to with at least one measure.

What is claimed is: 
     
         1 . A single-chip system, comprising:
 a memory management unit; and   a computing unit configured to:   receive a signal, wherein the signal describes an event;   evaluate the signal for determining infringement of one or more rules based on a set of rules, wherein the set of rules is embodied in hardware, wherein the set of rules comprise restrictions to the memory unit;   based on the evaluation of the signal and upon determination of an infringement of the one or more rules, respond to the infringement of the one or more rules with at least one preconfigured measure.   
     
     
         2 . The single-chip system of  claim 1 , wherein the computing unit is part of an inspection unit for monitoring a plurality of computing units or a virtual computing component of the single-chip system. 
     
     
         3 . The single-chip system of  claim 1 , wherein the set of rules is either unalterable in hardware or alterable using a secured method according to secret information encoded in the hardware in the single-chip system. 
     
     
         4 . The single-chip system of  claim 1 , wherein the computing unit is further configured to:
 determine event data corresponding to a cause of an event, a type of the event, and/or time of the event.   
     
     
         5 . The single-chip system of  claim 1 , wherein the computing unit is further configured to:
 pre-evaluate the signal transmitted to a further computing unit for filtering the signal.   
     
     
         6 . The single-chip system of  claim 4 , wherein the computing unit is further configured to:
 add a chip ID identifier to event data corresponding to the event on the internal memory device or the external memory device.   
     
     
         7 . The single-chip system of  claim 1 , wherein the set of rules comprise rules for logging events, for filtering information, for selection measures, and/or for classifying events. 
     
     
         8 . A method for operating a single-chip system, wherein the single-chip system comprises a memory management unit and a computing unit, the method comprising:
 receiving, at the computing unit, a signal, wherein the signal describes an event;   evaluating, at the computing unit, the signal for determining infringement of one or more rules based on a set of rules, wherein the set of rules is embodied in hardware, wherein the set of rules comprise restrictions to the memory unit;   based on the evaluation of the signal and upon determination of an infringement of the one or more rules, responding to the infringement of the one or more rules with at least one preconfigured measure.   
     
     
         9 . The method of  claim 8 , wherein the set of rules is either unalterable in hardware or alterable using a secured method according to secret information encoded in the hardware in the single-chip system. 
     
     
         10 . The method of  claim 8 , the method further comprising:
 determining event data corresponding to a cause of an event, a type of the event, and/or time of the event.   
     
     
         11 . The method of  claim 8 , the method further comprising:
 pre-evaluating the signal transmitted to a further computing unit for filtering the signal.   
     
     
         12 . The method of  claim 10 , the method further comprising:
 adding a chip ID identifier to event data corresponding to the event on the internal memory device or the external memory device.   
     
     
         13 . The method of  claim 8 , wherein the set of rules comprise rules for logging events, for filtering information, for selection measures, and/or for classifying events. 
     
     
         14 . A motor vehicle, comprising a control device that comprises a single-chip system, wherein the single-chip system comprises:
 a memory management unit; and   a computing unit configured to:   receive a signal, wherein the signal describes an event;   evaluate the signal for determining infringement of one or more rules based on a set of rules, wherein the set of rules is embodied in hardware, wherein the set of rules comprise restrictions to the memory unit;   based on the evaluation of the signal and upon determination of an infringement of the one or more rules, respond to the infringement of the one or more rules with at least one preconfigured measure.   
     
     
         15 . The motor vehicle of  claim 14 , wherein the computing unit is part of an inspection unit for monitoring a plurality of computing units or a virtual computing component of the single-chip system. 
     
     
         16 . The motor vehicle of  claim 14 , wherein the set of rules is either unalterable in hardware or alterable using a secured method according to secret information encoded in the hardware in the single-chip system. 
     
     
         17 . The motor vehicle of  claim 14 , wherein the computing unit is further configured to:
 determine event data corresponding to a cause of an event, a type of the event, and/or time of the event.
