A Comparative Analysis of Anonymous and Non-Anonymous Authorization Architectures for IoT Environments in Cooperative Intelligent Transport Systems

Abstract

In this paper, we present a comparative analysis of two distinct authorization architectures with a focus on their applicability in dynamic and cooperative intelligent transportation networks (C-ITS) suitable for low-powered IoT devices. Both architectures leverage accumulators for authorization and secret key storage, while our modification of the original architecture introduces an enhanced privacy feature enabling anonymous device access via a proxy node. This modification results in increased communication complexity, trading off anonymity against increased interaction overhead. We provide a proof of concept implementation with performance experiments, and conclude that the cryptographic computational performance remains relatively unaffected between the two architectures. Our findings suggest a potential for different deployment strategies of these architectures; in urban settings with a dense presence of proxy nodes, but also in sparser regions where privacy is not paramount due to minimal vehicle presence.
