Development Of Hybrid Cryptography Performance Optimization I: State Junction Node Communication Scenario in VANET

Abstract

Communication security in VANET networks is very important, especially in the scenario of state intersection nodes which are accident-prone points due to the high risk of collisions between vehicles. However, traditional cryptographic algorithms face constraints such as limited bandwidth, high power consumption, and computational complexity that limit their effectiveness in maintaining communication security in this area. Therefore, this study develops a more efficient and secure hybrid cryptographic optimization to improve communication reliability at intersection nodes, in order to ensure the safety and stability of VANET networks under highly dynamic conditions. This study uses a qualitative method with data collection through documentation from relevant written sources such as books and academic journals. Data analysis is carried out through three main stages: data reduction to structure information, presenting data in an easy-to-understand form, and drawing conclusions. The results show that hybrid cryptography proves to be an effective solution for enhancing communication security at junction nodes in VANET networks. Combining the speed of symmetric algorithms for bulk data encryption and the power of asymmetric cryptography for key exchange and authentication, this model is able to address the dynamic and complex communication challenges in vehicular environments. This approach significantly improves communication efficiency, security, and reliability. The implications of these results can serve as a basis for the development of more advanced security protocols that are adaptive to the evolving VANET network conditions.
