车辆到一切(V2X)通信依赖于量子对手打破的圆曲线签名,以及匿名证书,其匿名性取决于旋转率,而不是加密。这项工作介绍了qDGSP,一个后量子V2X基础设施:一个基于哈希的动态组签名计划(DGSP,超过SPHINCS+和WOTS+),分布在中央控制器和路边验证器之间。

Vehicle-to-Everything (V2X) communications rely on elliptic-curve signatures that a quantum adversary breaks and on pseudonym certificates whose anonymity rests on rotation rate, not cryptography. This work presents qDGSP, a post-quantum V2X infrastructure: a hash-based dynamic group signature scheme (DGSP, over SPHINCS+ and WOTS+) distributed between a central controller and roadside verifiers. Group keys derive deterministically from quantum key distribution (QKD) seeds served over the ETSI GS QKD 014 interface, so no group-signature secret crosses the classical channel. qDGSP-EA (Ephemeral
