Possibilities of manipulating recommendations of elements of the digital tachographs system and ways of preventing this action

A tachograph which belongs to the group of ORD devices is the oldest recorder (On Board Recording Devices), and the duty of taking it was led into the USA already in 1939. The inventor of the tachograph was Max Maria von Weber, an administrative official, engineer and author. The Hasler Event Recorder was introduced in the 1920s. Regrettably, the construction of analogue tachograph, an original type of tachograph used in road transport, encouraged to numerous frauds and counterfeits of social rules for drivers In order to solve these all problems, they led with Directive of Advice No. 2135/98 from 24 September 1998 of the August of 2004 from the beginning of in the area of the European Union, new type of registering setting up in the road transport - digital tachograph. In order to make it impossible to abuse, a complex system of keys was applied cryptological and of certificates, saved in grating and devices, letting for explicit determining entitlements of users and authenticities of data, cards and devices. In spite of using, the most modern keys and securing systems, with respect to elements of the system of digital tachographs a lot of modus operandi were observed so that they registered wrong sizes. The European Union took right action in order to before to prevent, nevertheless they must be implemented into the everyday life. Those paper is include information about level of manipulation of digital tachograph and their elements, ways of manipulations of digital tachograph and future ways of counteracting manipulations
