Alternative Applications of the SCMS V2X Infrastructure

Vehicle to Vehicle Safety Application using ECC PKI

IEEE 1609.2 and Connected Vehicle Security: Standards Making in a Pocket Universe

核心是满足v2v场景的限定条件:短时有效、匿名化、批量申请、字节数尽量少

适合可信节点的匿名化提交信息场景、可信身份的匿名化校验场景。。。

ecqv implicit certificate

SEC 4: Elliptic Curve Qu-Vanstone Implicit CertificateScheme (ECQV)

Implicit_certificate

字节数少通过ecqv的方式实现

butterfly key expansion

IEEE 1609.2 and Connected Vehicle Security:Standards Making in a Pocket Universe

A Security Credential Management System for V2X Communications

短时有效、匿名化、批量申请通过butterfly key expansion机制实现

paper

Schnorr-based implicit certification: improving the security and efficiency of V2X communications

这篇是讨论把cert的hash(即h值)的乘法,挪到CA的公钥点上,而不是像原来的临时中间点。

由于CA的公钥点固定,就可以提前算好,节省时间

Accelerating V2X Cryptography through Batch Operations

EE从PCA获得批量V2X证书时,通过把证书校验的左右式子分别批量加法,合并基点、PCA公钥的乘法,减少运算量

ECDSA*批量校验也类似,其实是基于PCA的公钥相同的预设。注意ECDSA*是ECDSA的变种。这个的问题在于,批量数目越大,平均等待时延也会随之增大,效果不好说。
