Embodiment Construction

[0042] The invention provides a free flow transaction system and method for ensuring the security of vehicle label information.

[0043] like figure 1 As shown, a free flow transaction method to ensure the security of vehicle label information includes the following steps:

[0044] S1. The roadside unit RSU2 allocates a dedicated uplink window to the on-board unit OBU1;

[0045] S2. OBU1 and RSU2 two-way authentication and transaction;

[0046] S3. RSU2 releases the link with OBU1.

[0047] S1 includes the following steps:

[0048] S11. If the OBU1 is used for the first time, the OBU security module 12 on the OBU1 uses the OBU key 11 to encrypt the identification information containing the OBU1 unique identifier OBUID and a group of random numbers to generate ciphertext;

[0049] S12.RSU2 sends broadcast signaling;

[0050] S13. After receiving the broadcast instruction from the RSU2, the OBU1 uploads the dedicated window request signaling carrying the ciphertext to the R...

Abstract

The invention provides a free stream trading method for guaranteeing the information security of an on-board tag. The free stream trading method comprises the following steps: S1, distributing a special upstream window to an on-board unit (OBU) by a road side unit (RSU); S2, carrying out bidirectional authentication and trading by the OBU and the RSU; S3, releasing links by the RSU and the OBU. A free stream trading system for guaranteeing the information security of the on-board tag comprises the RSU configured with an RSU secret key and the OBU configured with an OBU secret key; the RSU comprises an RSU security module, and the OBU comprises an OBU security module. The free stream trading system has the advantages and benefits that the information security of the on-board tag is effectively guaranteed in a free stream application, and thus the OBU is not illegally accessed to steal user information.

Description

technical field [0001] The invention relates to the technical field of information security in a multi-lane free flow non-stop charging system. More specifically, the identity OBUID reported by the vehicle tag is encrypted through software encryption and identity authentication. The reader needs to be authorized to recognize the correct tag identity and continue to interact with the tag to prevent The method by which tags are illegally identified and used. Background technique [0002] With the advancement of ETC national networking, ETC applications are becoming more and more accepted by people. More and more car owners begin to use ETC vehicle tags to experience the convenient travel experience brought by ETC. According to statistics, by 2015, ETC users will exceed 20 million. With the expansion of the scale of ETC, the expansion and application of ETC has become a hot spot that people pay attention to. ETC is mainly positioned in high-speed traffic. How to use existin...
