The state-of-the-art study, voyage et cie discount code Rishiwal et al.(2024) proposed a blockchain-based vehicular network framework designed to enhance communication security and protect vehicle privacy in vehicle-to-everything (V2X) communications.The proposed framework validates vehicle legitimacy using individual certificates and subsequently transmits data collected and integrated by intermediate entities to the blockchain, thereby avoiding direct exposure of vehicle privacy.However, the framework does not prevent intermediate entities from accessing vehicle privacy, leaving vehicles vulnerable to tracking and monitoring by these entities.In response to this limitation, this study proposes a key expansion method based on elliptic curve cryptography (ECC).

This approach employs a product two-stage key expansion process, referred to as “butterfly key expansion,” to ensure that vehicle privacy is not exposed to any device within the V2X communications.Experimental results demonstrate that the key expansion time does not significantly differ from the key generation time.Furthermore, the signature generation and verification times using the expanded keys are comparable to those of the original keys.These findings indicate that the proposed method achieves enhanced privacy protection without imposing additional computational overhead.
