Vehicle infrastructure cooperative security communication method based on hash encryption

Abstract

The invention relates to a vehicle infrastructure cooperative security communication method based on hash encryption. The method comprises the following steps: step 1), mixing connection request information and a PIN code into a secondary character string by an information sender, wherein the PIN code is a unique identification code corresponding to the information sender; step 2), performing hash encryption on the secondary character string, and generating a corresponding hash value; and step 3), maintaining a database that stores multiple hash values by an information receiver, after receiving the hash value in step 2) by the information receiver, traversing to find the database, and judging whether the received hash value is valid; if yes, then establishing a secure communication connection with the information sender; otherwise, refusing the connection. Compared with the prior art, the vehicle infrastructure cooperative security communication method based on the hash encryption provided by the invention has the advantages of being high in security, and capable of realizing access control and so on.

Description

technical field [0001] The invention relates to the field of vehicle network and vehicle safety communication, in particular to a vehicle-road collaborative safety communication method based on hash encryption. Background technique [0002] The development of the Internet of Vehicles in the future will depend on the development of its security technology. In the Internet of Vehicles based on DSRC communication technology, the vehicle is connected through the on-board OBU and the drive test system RSU, but the connection cannot always be maintained, and the connection is intermittent, because the RSU is a single device and its communication range is relatively short. However, identity authentication is required every time information is exchanged with the RSU, which significantly reduces the communication quality. In terms of authentication methods, digital certificates are also used for identity authentication, but the current number of cars in my country is 140 million, wh...

AI Technical Summary

Problems solved by technology

In the IoV based on DSRC communication technology, the vehicle is connected through the on-board OBU and the drive test system RSU, but the connection cannot be maintained all the time, and the connection is intermittent, because the RSU is a single device and its communication range is short

And every time information exchange with RSU, identity authentication is required, which obviously reduces the quality of communication

In terms of authentication methods, digital certificates are also used for identity authentication, but the current number of cars in my country is 140 million, which will undoubtedly greatly increase the burden of key management and certificate management, and also reduce the efficiency of authentication
