Batch Verification of High-efficient Short Group Signatures
Shaozhen Chen · Jisuanji gongcheng · 2010
The vehicular networks for safety messaging have particular requirements on the applicable cryptographic primitives.It requires that cryptographic overhead is low and many messages from many different signers are verified very quickly,and moreover that is privacy-friendly.This paper adopts the small exponents test,takes advantage of the peculiarities of bilinear maps,and proposes an efficient batch verifier for a short group signature scheme to satisfy all three above requirements,with a verification time where the dominant operation requires only two pairings.
