DIGITPOL

Digitpol invented a security device for a vehicle’s electronic system. The vehicles electronic system comprises a Control Area Network and our device is the only security system to prevent unwanted traffic and malware.

Our success

Our company is a leader in combatting vehicle crimes and therefore the writeblocker is a major contribution towards the fight against vehicle crime as it has abilities to prevent the coding of a second key and keyless theft.

Background Art:

A recent study has shown that although the number of car thefts in the EU has fallen by 12% over the last five years, the total value of cars stolen has increased by 51 % over the same period. The increase in value is due predominantly to the fact that the cars are now being stolen at a much younger age than was heretofore the case. Of the cars stolen in the EU, 72% are now estimated to be only between 1 and 5 years old. This represents a massive problem for insurers. These figures are taken from official European police figures provided by the Dutch national institute against vehicle crime.

It has also been estimated that 82% of all cars stolen in the EU are stolen by unscrupulous individuals exploiting the vulnerabilities of the On-Board Diagnostics (OBD) plug. Once access to the OBD plug has been gained, the connection to the OBD plug can be used to communicate with one or more engine control units (ECUs) or modules via the Control Area Network (CAN) Bus. This connection can be used to turn off the immobiliser module, thereby allowing the car to be started with practically any key, or can be used to allow access to the key programming module thereby allowing programming of a new key for the vehicle.

Digitpol a leader in Automotive security, our commitment to develop this project to all levels in cooperation with partners is because we understand the current problems in connected car security and real status of vehicle crime and security.

The Patented Solution

In one embodiment of the invention there is provided a security device in which the means to detect whether a valid ignition key has been presented in the vehicle comprises means to detect a communication on the CAN Bus from an immobilizer ECU indicative that a valid ignition key has been presented in the vehicle. This is seen as a simple way to determine whether or not a valid ignition key has been presented and will require the immobilizer to be activated in order to operate. This embraces the inherent security of the immobilizer in the vehicle resulting in a robust, secure device. In one embodiment of the invention there is provided a security device in which the means to detect a communication on the CAN Bus from an immobilizer ECU indicative that a valid ignition key has been presented in the vehicle comprises means to detect a communication on the CAN Bus from the immobilizer ECU to operate a fuel pump. As this requirement is highly specific and requires that the immobilizer security protocols have been fully satisfied before it will send a communication to the fuel pump, the device is seen as particularly secure as it benefits from the full security mechanisms of the immobilizer module. In one embodiment of the invention there is provided a security device in which the means to detect a communication on the CAN Bus from an immobilizer ECU indicative that a valid ignition key has been presented in the vehicle comprises means to detect a communication on the CAN Bus from the immobilizer ECU to operate a start engine.

If a data table is provided, when a write command is received at the input , the write command is checked against the list of write commands and if the write command matches one of the valid write commands in the data table, the write command is allowed to proceed from the output to an ECU. If however the write command does not match a valid write command in the data table, the write command will be terminated and not allowed to proceed to an ECU.
