With the rapid development of edge computing and intelligent maritime transportation systems, secure authentication and key agreement protocols have become essential for protecting communications among maritime entities and edge devices. Recently, Mahmood et al. proposed an authentication protocol for edge-centric maritime transportation systems, claiming that their scheme can resist various security attacks while ensuring efficient communication. However, practical maritime environments still face many security threats. In addition, edge infrastructures usually have limited resources. Therefore, authentication protocols require rigorous security evaluation. In this paper, we perform a crypt... More >
