Asymmetric cryptographic solutions for VANET.

Asymmetric Cryptographic solutions	Security Requirements support	Limitations
Anonymous keys and certificates.	Authentication/Availability/Privacy Preservation	Computational hardness
ID-based proxy signatures	Authentication/Privacy Preservation/Non-Repudiation	Vulnerable to reveal private key
Elliptic Curve Cryptography	Authentication/Availability/Privacy Preservation	Vulnerable to replay attack
RSU-aided Authentication Methods	Authentication/Privacy Preservation	Compromise on an RSU can result in disclosure of information
Smart Cards for identification	Message authentication/privacy preserving	Storage
