Development of Data Security Algorithms in V2V Communication

In the context of vehicular communication, data security is a critical concern. This paper presents an improved version of the LED (Lightweight Encryption and Decryption) block cipher, specifically designed to enhance security in resource-constrained environments. Our modifications introduce additional encryption rounds and a refined key management scheme, increasing the complexity and difficulty of unauthorized data tampering. These enhancements significantly bolster the cipher's resilience against cryptographic attacks while maintaining the lightweight characteristics necessary for wehicular applications. Comparative analysis with the standard LED cipher demonstrates that our approach offers improved security and performance, making it suitable for secure data transmission in automotive systems.memory.
