Embodiment Construction

[0210] Mutually corresponding components of the following embodiments are denoted by the same reference numerals.

[0211] Figure 1A with Figure 1B A first embodiment of an exemplary system for tamper-proof storage of vehicle data 110 , 310 , 510 , 610 for a vehicle in a blockchain 204 is shown. The means of transport is, for example, an automobile such as a sedan. The vehicle includes a vehicle computer system 100 . The vehicle computer system 100 has a memory 102 in which a public key 106 of an asymmetric key pair assigned to the vehicle is stored. In addition, stored in the memory 102 are vehicle data 110 of the vehicle, received by the vehicle computer system 100 from sensors 130 , 150 , 170 of the vehicle itself or from the computer system 300 of the factory. The vehicle data can include, for example, vehicle mileage. The memory 102 also includes a protected memory area 104 that is only accessible by the processor 112 of the vehicle computer system 100 and in which...

Abstract

The invention relates to a method for tamper-proof saving of vehicle data (110, 310, 510, 610) of a vehicle in a blockchain (204). The method comprises: creating a signed output instruction for outputting a vehicle certificate (282), having a data record characterizing the vehicle, using the blockchain (204), in the case of a valid signature, receiving the vehicle certificate (282), outputting thevehicle certificate (282), wherein the output vehicle certificate comprises a machine-readable code (284), wherein the machine-readable code (284) comprises a private cryptographic key of an asymmetric key pair, wherein a public cryptographic key of the asymmetric key pair is identified in the blockchain (204) as a test value for testing a signature of a read request for reading vehicle data of the vehicle certificate (282) from the blockchain (204).

Description

technical field [0001] The present invention relates to a method for creating a vehicle certificate using tamper-proof stored vehicle data in a blockchain and a system for performing the method. Background technique [0002] The identity of the means of transport is generally certified by an official means of transport certificate, for example, in the case of a motor vehicle, by a license. Although such licenses are generally protected by security features, they offer only limited protection, especially compared to the value of the means of transport to be protected thereby. [0003] There is also the danger that if the permit blank form is stolen from the permit issuing office, it too will fall victim to theft. These permits, for example, already have a serial number on file and are issued by a car thief to a stolen vehicle. Contents of the invention [0004] The invention is therefore based on the task of providing an efficient and secure method for the tamper-proof cr...
