Algorithm 1: An adaptive, lightweight, secure, and efficient RFID-based authentication scheme for IoV.

$T a g_{i}, R_{j}$ Register with the cloud; the cloud synchronizes the RID to the edge server after hashing and encryption

$R_{j}$ broadcast $M_{1} : {Q u e r y, R_{j 1}, R_{j 2}, T_{1}}$ to the surrounding area, where

$R_{j 1} = n_{r} G$ , $R_{j 2} = R I D_{j} \oplus n_{r} P$ .

$T a g_{i}$ receive $M_{1} : {Q u e r y, R_{j 1}, R_{j 2}, T_{1}}$

if $T_{2} - T_{1} \leq Δ T$

compute $R I D_{j} = R_{j 2} \oplus k R_{j 1}$

if $r i d = = R I D_{J}$
