In recent years, with the rapid development and widespread application of vehicle networking technology, vehicle networking information security problem has become a hot spot in this field. Vehicle networking's characteristics consist of large scale, opening wireless channel and foreseeable track. The attacker can wiretap the broadcast messages in the wireless channel, analysis the data, forecast the track and then track vehicles, which seriously threatens the information security of car networking. Especially for the car networking of hazardous chemical substance logistics vehicles, if attacked by hacker, it could cause vicious events such as the leakage of hazardous chemical substance, explosion and even fatal traffic accidents. This not only causes serious losses to our life and property, but also damages the ecological environment along the way. Therefore, the network security for car networking of hazardous chemical substance becomes a critical scientific problem in this field, which needs to be solved urgently.Considering the network security problem of hazardous chemicals logistics vehicles for networking, and combined with the specific needs of the project, the encryption algorithm for hazardous chemicals logistics vehicle networking information security is researched.

Combined the project user needs, the encryption technology and FPGA to achieve secure communication vehicle networking is proposed;(2)The advantages and disadvantages of symmetric encryption algorithm and asymmetric encryption algorithm are researched, and according to the information characteristics of hazardous chemicals logistics Vehicle networking, two kinds of representatives encryption algorithm-AES and RSA are selected. Pipelining is used in AES algorithm to save hardware occupied area. Concerning the low speed of RSA algorithm for modular exponentiation and modular multiplication and the application scenarios of RSA encryption algorithm in a hybrid system, the L-R Free Scan modular exponentiation and avoiding minus 2 Montgomery algorithms are combined to simplify RSA modular power multiplication and improve RSA computing speed.(3)FPGA technology and application development platform are researched and the hybrid encryption algorithms is completed with the use of FPGA technology. The BD2 vehicle location data information is encrypting and decrypting. Each module is programmed and simulated with Verilog and test documentation for part of the vehicle position information is documented. The simulation and verification of the 128 bit key length AES and RSA algorithm encryption algorithm hybrid system are carried out with Modelsim software. Software program is decrypted in the monitoring center, which verifies the advanced nature and feasibility of this encryption algorithm. At last, the research work achieves the expected results.Finally, the research work is concluded, and the prospect of further work is described.
