Embodiment Construction

[0015] The details of the present invention will be further described below in conjunction with the accompanying drawings.

[0016] Refer to the attached figure 1 , specifically explain the process of data security transmission technology based on the traditional SSL / TLS protocol:

[0017] 1) Node A initiates a request: first, A sends a Hello message to B, and sends the protocol version, cipher suite, and compression algorithm it supports to B together with a random number RandomA, which will be combined with the subsequent random number generated by B. Make up the key. The cipher suite consists of key exchange algorithm, signature authentication algorithm, message digest algorithm and symmetric encryption algorithm;

[0018] 2) Node B responds: When B receives A's hello request, it determines the supported SSL / TLS protocol version, cipher suite, and compression algorithm from the parameter list provided by node A. At the same time, generate a random number RandomB, send it...

Abstract

The invention discloses an Internet of Vehicles data secure transmission technology based on an improved SSL / TLS protocol, and belongs to the field of Internet of Vehicles. Due to the fact that a wireless communication mode is adopted between nodes of the Internet of Vehicles, man-in-the-middle attacks exist in the data transmission process, and information confidentiality and integrity are reduced. Aiming at the requirements of the Internet of Vehicles communication on safety and real-time performance, the invention designs a data safety transmission technology based on an improved SSL / TLS (Secure Sockets Layer / Transport Layer Security) protocol. The technology comprises two stages: in a key negotiation stage, the security of a key is ensured through asymmetric encryption, and in a data encryption transmission stage, the encryption and decryption time of communication data is reduced through symmetric encryption. And then, aiming at the problem that the SSL / TLS protocol is unsafe andtimely delayed in key negotiation due to a single-point fault of a certificate authority and low asymmetric encryption speed, the SSL / TLS protocol is improved by utilizing a block chain and cookie technology. Compared with the prior art, the improved SSL / TLS protocol disclosed by the invention is greatly improved in the aspects of security and efficiency of key negotiation.

Description

technical field [0001] The invention relates to the field of the Internet of Vehicles, and particularly designs a technology for secure transmission of data in the Internet of Vehicles based on the improved SSL / TLS protocol. Background technique [0002] With the development of industrial modernization, the automobile industry has developed rapidly, and automobiles have become the most important part of the urban transportation system. A recent report pointed out that the number of vehicles used in the world has exceeded one billion, and it is estimated that by 2035 there will be to 2 billion. With the continuous development of modern transportation and the updating of automobile manufacturing technology, although it brings great convenience to people's life, various traffic problems also occur frequently. When the vehicle is running on the road, due to various factors, such as the driver's condition, bad weather conditions, poor road conditions, road traffic congestion and...
