Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings. The embodiments of the present invention include but are not limited to the following examples.

[0021] Related terms are explained as follows:

[0022] Vehicle Internet of Things Terminal (T-BOX for short): internally uses GPS / BD positioning module and communicates with the monitoring platform through the GRPS network, maintains real-time communication with the vehicle engine controller through the CAN bus interface, and uploads the collected data to the monitoring platform in real time . So as to realize real-time supervision and control of vehicles.

[0023] GPS / BD: Satellite positioning module, providing position information and timing functions.

[0024] MD5 Algorithm: (MD5 Message-Digest Algorithm), a widely used cryptographic hash function that can generate a 128-bit (16-byte) hash value to ensure complete and consistent information transmission.

Abstract

The invention discloses a T-BOX anti-dismantling method and system based on an MD5 dynamic encryption algorithm. The method comprises the following steps: setting private keys for the T-BOX and an ECU; timing the ECU by the T-BOX; randomly generating 8-byte data inside the ECU and sending the 8-byte data to the T-BOX; calculating a key according to the clock by the T-BOX; adopting the MD5 encryption algorithm to obtain a result and sending the result to the ECU by the T-BOX; calculating to obtain a result by the ECU according to the same method for comparison; and comparing the two results, ifthe two results are the same, then judging that handshake verification is correct, and a vehicle works normally, and if the two results are not the same, then waiting for 5 seconds and sending the handshake verification again, if the two handshake verifications are wrong, then performing vehicle locking control on the vehicle by the ECU. The T-BOX anti-dismantling method based on the MD5 dynamicencryption algorithm provided by the invention solves the problems in the prior art that the vehicle cannot be supervised and controlled, and the vehicle is maliciously owed or stolen since the vehicle Internet of Things monitoring terminal, namely the T-BOX, assembled on a financially mortgaged vehicle of the construction machinery industry is maliciously dismantled.

Description

Technical field [0001] The invention relates to the field of engineering machinery, and in particular to a T-BOX anti-dismantling method and system based on an MD5 dynamic encryption algorithm. Background technique [0002] At present, the prices of vehicles in the construction machinery industry are basically relatively expensive. For example, large excavators and cranes sell for more than one million. Therefore, most manufacturers use financial mortgages and installment payments. However, the location of the vehicle is different from that of the real estate. In order to better monitor the vehicle, the vehicle is installed with T-BOX equipment during production. The equipment can track the vehicle location and working condition information in real time. When repayment, the monitoring platform can lock the car remotely. In addition, if the T-BOX device is maliciously removed, the car can be judged by regular handshake verification, which can realize the automatic locking functio...
