Title:
Cryptanalysis of an Ultra lightweight Authentication Scheme based on Permutation Matrix Encryption for Internet of Vehicles
Authors: Morteza Adeli, Nasour Bagheri
Abstract:Internet of Things (IoT) has various applications such as healthcare, supply chain, agriculture, etc. Using the Internet of Vehicles(IoV) to control traffic of the cities is one of the IoT applications to construct smart cities. Recently Fan et al. proposed an authentication protocol to provide security of the IoV networks. They claimed that their scheme is secure and can resist against various known attacks. In this paper, we analyze more deeply the proposed scheme and show that their scheme is vulnerable against disclosure and desynchronization attacks. In disclosure attack, we disclose unique identification of the tag ID, secret key S, encryption matrix M_2 and half rows of encryption matrix M_1. Furthermore, we proposed an improved authentication scheme based on Maximum Distance Separable(MDS) matrices that is resistance against various attacks while maintaining low computational cost.
