The invention relates to equipment designed to prevent unauthorized use of the vehicle or theft.
Various methods and systems of protection against vehicle theft. These systems, using the radio channel, as a rule, contain the receiving device installed on the vehicle, and a portable transmitting device user, keychain, in the process of operation by the transmitting device to create a code package using the individual encryption key and betray code parcel in the receiving device. Such systems during their operation can be quite effective. This is especially true for systems that during the formation of the code make use of an individual encryption key, which is not transmitted from the portable transmitting device to the receiving device.
However, there is a possibility of interception of private encryption key during reprogramming or how is called this process "learning" of such systems. The process of reprogramming is the process during which from the portable transmitting device of the user at the receiving device is transmitted all the data necessary for approval of their work, including data required for the formation of the individual encryption key.
CCA is dangerous military situation, when flashing the system provoked by the attackers. It can occur when the process is properly functioning security systems with the aim of creating failures in the system broadcast radiate interference with the help of special equipment. In this case, the system owner may find that it is defective and you want to make "learning" system. In this case, if the necessary information is transmitted via a radio channel, it is impossible to guarantee that all the information required for opening a car alarm system, will not be intercepted using the device of signal interception (grabber) used by the attacker. Further dissection of the most reliable systems becomes the attacker rather simple task.
There are various technical solutions automotive security systems.
In the patent RU 2295466, publication 20.03.2007, IPC B60R 25/00, "Anti-theft alarm system for vehicle" describes a system containing a Central radio and Autonomous electronic modules, security anti-theft systems that communicate by radio with a Central LAN. Between the electronic module and the Central module is dynamic identification dialogue with the code signal parcels with numbers varying randomly from the silky to the parcel.
In the application JP 2007085007, publication, 05.04.2007, IPC B60R 25/00 described system radio control door with the electronic key. The system includes a transmission device of the first radio signal 49 and the electronic key transmitting the second radio signal including the cipher code unique to the vehicle. When the cipher code included in the radio signal received from the communication device, coincides with the unique cipher code for the car, and the key opening the door approaches the car, the door opens.
In the application US 2005268088, publication 01.12.2005, IPC B60R 25/00 described control system of the vehicle in which the mobile device sends the cipher code based on pre-stored data. The control device in the vehicle decrypts the received cipher code based on pre-stored data to generate commands for the equipment. Schema memory is designed to store data, including the key code and an identification code, which are the source of the cipher code. The control system of the vehicle creates a cipher related data by reading data from the memory circuit and exposing the data processing determined in advance.
In the considered systems is not compromised way of reprogramming, "learning" systems at real or imaginary her fault.p> The closest is the system disclosed in the patent US 6181252, publication 30.01.2001, IPC B60R 25/00, in which the disclosed system remote control with transmitter and receiver with parcels indulging across the airwaves, with a floating code. To create an encrypted parcels with floating code uses the exclusive OR operation with the permanent code and dynamic code. Code that is specific to each management system, is used as a permanent code so that a logical operation XOR, was different from system to system as a result of various encryption methods for each system. The key code is set in the process control system, so that the floating code cannot be decoded as long as the key code is stored unopened. This system ensures high reliability in operation. However, this system is not immune from the decryption key code (encryption key) in the process of reprogramming, including when training initiated by the attackers.
Technical result achieved in this invention, is to reduce the risk of interception and decryption of information, in particular encryption codes transmitted between the portable transmitter and receiver mounted on the vehicle, about the Jesse reprogramming "learning" system. To reduce this risk significantly increases the effectiveness of most of the car security systems.
The way security car alarm system from unauthorized use, where the system includes a receiving device installed on the vehicle, and a portable transmitting device of the user. According to the method in the operation of the system using a transmitting device, create code package using the individual encryption key and betray code parcel in the receiving device. The method differs from the known fact that in the process of reprogramming the system, in particular, in the case of a real or imaginary system malfunction, the exchange of information between the portable transmitting device and the receiving device installed in the vehicle, carried out through a communication channel, thus choose the communication channel that does not use the radio.
Use in reprogramming, "learning", canal system, which uses a radio signal, leads to the fact that the attackers witness with his electronic equipment for the radio, can't get the information they are interested, in particular, the encryption keys. This fact obstructs the ability to decrypt the security system auto is obile and abduction.
In particular, in the process of reprogramming the exchange of information between the portable transmitting device and the receiving device installed in the car, realized by means of optical, or acoustic, or induction channels. The transmission of information through the channels of this physical nature can improve its stealth. Optical channel can be run narrow, which reduces the possibility of data interception. Acoustic and induction channels, you can do low-power, that will not allow you to capture information from a considerable distance.
In another particular case, in the process of reprogramming the exchange of information between the portable transmitting device and the receiving device installed in the vehicle, carry out, either through a wired connection.
In addition, when creating the code make an individual encryption key is formed using the manufacturing code and individual number of the transmitting device of the user, while the manufacturing code is defined as an individual code for each instance of car security system. Currently, quite often the same manufacturing code sets all specific systems of this brand burglar alarm. Assignment of individual manufacturing code of each system is the point of this brand along with the individual number of the transmitting device dramatically increases the effectiveness of security systems.
In addition, the above-mentioned encryption key during operation do not transmit in the transmission code of the parcel in the receiving device. It also increases the effectiveness of security systems.
The proposed way to improve the security of security systems from opening the car can be used in the newly created systems of protection against theft and theft, but may also be used for upgrading existing systems.
The invention is illustrated by the figure.
In Fig.1 presents a diagram of the security car alarms when using hardware capture code signal.
The alarm system of the vehicle 1 (Fig.1) contains a wearable radiating device 2 (keychain) for the transmission code of the parcel or parcels on the radio channel, the receiving device 3 installed on the car. Other elements of the system not shown in the figure. For explanation of the invention sufficient to carry the device 2 provided only radiation of a parcel using the individual encryption key, and the receiving device 3 provided a reception signal with a code packages. The invention is also operable in case of applying it to more complex systems that provide two-way radio communication between the portable device 2 and the receiving device 1. In Fig.1 also poisonousness 4 interception code sending the radio signal, radiated wearable transmitter 2.
The proposed method is as follows.
If there is a need to carry out reprogramming system, when its actual failure, or when jamming attackers, reprogramming are not, as is the case in existing systems, through the same channel that is used in the operation of the system, and use the other channel, excluding the radio. This eliminates the interception of information, which should contain and contains encryption code to the radiating device, the transmitter and the receiving device on the vehicle agreed data and could in the operation mode, to work together. This transmission with the aim of improving security should be done at low power signals or with the exception of the external radiation.
This communication channel can be an optical channel, for example, focused infrared signal of small capacity.
In addition, can be applied acoustic channel, or induction conduit, small power next to the car.
The most secure would be the channel of transmission of information by wire, by connecting the transmitter with the receiver via a cable with MINI-USB connector.
For i.e. monitoring) reference and information transfer on the proposed channels can be used a known device transmission and reception.
Enhancing the effectiveness of the method is that programming car alarm system so that in operation an individual encryption key is formed using the manufacturing code and individual number of the transmitting device of the user, while manufacturing code individual code for each instance of car security system. At the same time the encryption key in the process of operation is not transmitted in the transmission code of the parcel in the receiving device.
Due to the increased security of wired and focused infrared channels in the proposed method from the wearable device in the process of "learning", so was the possibility of upgrading existing systems may be transferred himself an individual encryption key. It can be formed just as it is done in technology KeeLoq - from manufacturing code and the serial number of wearable devices. This method eliminates the need to keep manufacturing code in the memory of the receiving device, which eliminates his "calculation" when recording the serial numbers of portable devices while operating a car alarm in normal mode, even if the attackers "read" the program receiving device.
The proposed method allows to improve the IC security security systems from unauthorized use.
