Problems solved by technology

However, this method relies heavily on RSUs
In addition, once the smart card is lost or stolen, it is easy for an attacker to impersonate a legitimate user to obtain the communication content in the network
[0006] To sum up, the existing security authentication algorithms have the following problems: 1) the calculation is complex and the storage overhead is large, and they are not suitable for large-scale vehicular ad hoc networks; 2) the digital signature processing time is too long so that the driver does not have enough time to take relevant driving measures to avoid traffic accidents; 3) by smart card loss attack, offline password guessing attack, replay attack, masquerading attack, etc.
The disadvantage is that the invention has the disadvantages of large authentication overhead and communication overhead

Embodiment Construction

[0068] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0069] Such as image 3 The illustrated embodiment is a smart card-based security authentication method for a vehicular ad hoc network. The mobile node of the vehicular ad hoc network is a terminal located on a car, and the terminal includes a wireless transceiver module, a microprocessor and a memory; The speed sensor installed on the car is electrically connected to the GPS locator. If there is any data detected by the above device, please reflect it in the steps; the mobile node is connected to the base station wirelessly, and the base station is connected to the authentication server through wireless; The identifier of the base station is stored; it includes the following steps:

[0070] Step 100, such as figure 1 As shown, user V i Submit the identifier to the authentication server before entering the network and Has...

Abstract

The invention discloses a safety certification method of a vehicular adhoc network based on an intelligent card. The user identity certification method is based on a one-way hash function and a simple bitwise XOR operation, and is small in calculation amount and suitable for achieving the intelligent card. The method is used for verifying the identity legality of a vehicle user. The method has the advantages of being capable of resisting the attack from the losing of the intelligent card, resisting the attack of off-line password guessing, resisting replay attacks, resisting the attack of base station capturing, and being low in calculation cost and communication cost.

Description

technical field [0001] The present invention relates to the technical field of wireless communication. The present invention relates to a security authentication method based on a smart card for a vehicle-mounted ad hoc network capable of resisting smart card loss attacks, offline password guessing attacks, replay attacks, and base station capture attacks, and reducing communication overhead and computing overhead. . Background technique [0002] With the rapid development of key technologies such as wireless communication technology, on-board embedded computing, and various on-board sensors, Vehicular Adhoc Network (VANET) is considered to be a very large-scale mobile ad hoc network with a high degree of practicality. The vehicle-mounted ad hoc network is a safe, fast, effective, and open-structured vehicle-to-vehicle communication intelligent transportation system composed of vehicles and vehicles, vehicles and roadside units (Roadside Units, RSUs), which can realize accid...
