Use of cryptography principles in digital registration devices

Cryptography is a field of science necessary to solve problems with encryption of classified messages. The security of electronic information is an integral part of the digital tachography system. From year to year, there is a noticeable increase in electronic data logging systems in many aspects of life. The control measures created for the purpose of performing roadside checks are not sufficient to detect all violations in the recording equipment. Many violations that have occurred during the use of the vehicle are stored in the device’s memory. The article describes the basic mathematical rules illuminating cryptography. The hazards to which the motion sensor installed in the vehicle may be exposed are described. Breaking safety in transport systems may lead to incorrect results of inspections carried out while the vehicle is stopped by authorized services. The article also provides information on the authorities responsible for issuing cards for digital tachographs. Nowadays, documents are increasingly issued with the use of a digital signature. The digital signature of its origin is based on the principles of cryptography. The security key seems to be complicated for the average user. The article discusses the topic of tachograph construction, in particular the schematic responsible for information encryption.
