On the anonymity of one authenticated key agreement scheme for mobile vehicles-assisted precision agricultural IoT networks

Abstract

Smart farming uses different vehicles to manage all the operations on the farm. These vehicles should be put to good use for secure data transmission. The Vangala et al.'s key agreement scheme [IEEE TIFS, 18 (2023), 904-9193] is designed for agricultural IoT networks. In this note, we show that the scheme fails to keep anonymity, instead pseudonymity. The scheme simply thinks that anonymity is equivalent to preventing the real identity from being recovered. But the true anonymity means that the adversary cannot attribute different sessions to target users. To the best of our knowledge, it is the first time to clarify the differences between anonymity and pseudonymity.
