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

Abstract

The invention discloses a smart card-based security authentication method for a vehicle-mounted self-organizing network. The user identity authentication method in the present invention is based on a one-way hash function and a simple bitwise XOR operation, and has a small amount of calculation and is suitable for the realization of a smart card. The invention verifies the identity legality of the vehicle user. The invention has the characteristics of being able to resist smart card loss attack, off-line password guessing attack, replay attack, base station capture attack and low calculation and communication expenses.

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, vehicle embedded computing and various vehicle sensors, Vehicular Adhoc Network (VANET) is considered to be a very large-scale mobile ad hoc network with high practicality. The vehicle-mounted ad hoc network is a safe, fast, effective, and open-structure intelligent transportation system composed of vehicles and vehicles, and vehicles and roadside units (RoadsideUnits, RSUs). It can realize applications such as accident warning and assisted dri...
