摘要

随着车联网（IoV）的兴起，安全高效的身份验证对于防范网络威胁至关重要。本文提出了一种基于零知识证明（zk- snark）和椭圆曲线密码学（ECC）的会话密钥建立协议，包括椭圆曲线Diffie-Hellman （ECDH）密钥交换，以保证隐私和效率。虽然zk-SNARK计算引入了额外的验证开销，但我们的优化，如预先计算的证明参数和轻量级会话重新身份验证，减轻了延迟。性能评估显示，与现有方法相比，计算开销减少了20%，重新认证时间缩短了75%，使其成为现实世界车联网应用的安全实用解决方案。

Authentication protocol for vehicular networks using Zero-Knowledge Proofs and Elliptic Curve Cryptography

With the rise of the Internet of Vehicles (IoV), secure and efficient authentication is essential to prevent cyber threats. This paper proposes a session key establishment protocol using Zero-Knowledge Proofs (zk-SNARKs) and Elliptic Curve Cryptography (ECC), including the Elliptic Curve Diffie–Hellman (ECDH) key exchange, to ensure privacy and efficiency. While zk-SNARK computations introduce additional verification overhead, our optimizations, such as precomputed proof parameters and lightweight session re-authentication, mitigate delays. Performance evaluation shows a 20% reduction in computation overhead and a 75% faster re-authentication time compared to existing methods, making it a secure and practical solution for real-world IoV applications.
