Embodiment 1

[0080] like Figure 1-5 As shown, a wireless electronic license plate includes a microprocessor module, and the microprocessor module is used to communicate with a host computer, a WIFI module, a 3G communication module, and a GPS positioning module through a serial port, and at the same time realize system encryption and data processing, The microprocessor module is used to implement system encryption and data processing functions, and the microprocessor module encryption and processing method includes the following steps, step A: performing SHA encryption signature on the data; A1, filling additional messages, and inputting message M Padding is performed to ensure that the length of the padded message is an integer multiple of 512; A2, parse the padded message; A3, Hash calculation of SHA-256; Step B: Perform AES block encryption; in order to meet the requirements of AES, the block length is It is fixed to 128 bits, and the key length is variable to 128, 192 or 256 bits; in ...

Embodiment 2

[0090] An encryption method for a wireless electronic license plate, wherein the data transmitted from the wireless communication module of the microprocessor module is encrypted and processed, and the method specifically includes the following steps:

[0091] Step A: Perform SHA encryption signature on the data;

[0092] A1, pad the additional message, and pad the input message M to ensure that the length of the message after filling is an integer multiple of 512; the padding method is as follows, assuming that the length of the message M is 1 bit, then append a "1" and a "1" to the end of the message. k "0", so that l+l+k=448 mod 512; then fill in the binary representation of the original length l in the following 64 bits; for example, a message "abc", a total of 8x3=24 bits, then Then fill in 1 "1" at the back, then 448-(24+1)=423 "0", and finally fill in the original message length value of 24, which constitutes a 512-bit message;

[0093]

[0094] A2, parse the filled...

Embodiment 3

[0132] like Figure 7-8 As shown, a security encryption system for a right wireless electronic license plate, the wireless communication module is used for receiving and transmitting data; the microprocessor module is used for receiving the data transmitted by the communication module, encrypting the data, and performing identity authentication and authorization; The microprocessor module includes a chip sub-module, and a system sub-module, a memory sub-module, a clock sub-module, a data security and integrity sub-module, an analog sub-module, a timer sub-module, a communication interface sub-module, a human Machine interface sub-module; the data security and integrity sub-module is used to encrypt data, and the process of identity authentication and authorization is divided into security encryption system, identity recognition and authorization system, and the security encryption system uses SHA256 hashing Function, AES256 advanced encryption algorithm, transmission protocol ...

Abstract

The invention belongs to the wireless communication technical field and relates to a wireless electronic license plate, an encryption method and encryption system of the wireless electronic license plate. The wireless electronic license plate is characterized in that the wireless electronic license plate composites a microprocessor module; the microprocessor module is used for realizing encryption and data processing functions of a system; the microprocessor module communicates with an upper computer, a wireless communication module and a GPS positioning module through serial ports; the wireless communication module is used for completing data transmission in a network; the GPS positioning module is used for realizing the positioning of a vehicle; the microprocessor module is also connected with a camera; and the camera is used for monitoring the information of the surrounding of the vehicle. The electronic license plate of the invention can acquire vehicle information in real time; a traffic control department can locate the coordinates of a motor vehicle in an urban area range based on the electronic license plate; and the license plate can be networked, and therefore, the real-time information of the vehicle can be transmitted to the computer of a control center or a user.

Description

technical field [0001] The present invention relates to wireless communication technology and security communication technology, in particular to a wireless electronic license plate, its encryption method and encryption system. Background technique [0002] With the development of my country's economy, the number of automobiles has continued to rise, and so far, it has exceeded 140 million. This has led to a sharp increase in road traffic pressure; traffic violations and traffic accidents are increasing. Real-time, effective and refined vehicle supervision is an urgent need for urban traffic supervision. However, most of the urban vehicle traffic supervision is in the primary stage of manual inspection by the traffic police for the corresponding licenses (driving licenses, driver's licenses) of the iron license plates. Although there are video image projects such as red light violation snapshots and public security checkpoints, they can only complete the public security tra...
