A Note on One Authentication and Key Agreement Scheme for UAV-Assisted VANETs for Emergency Rescue

Abstract

We show that the key agreement scheme [IEEE TNSE, 1454--1468, 2004] is insecure against ephemeral secret leakage attack and smart card loss attack, not as claimed. This failure results from its simple encryption, in which only bitwise XOR operations are used to encrypt the messages.
