Continuous Entity Authentication in the Internet of Things Scenario

In the context of Internet Things (IoT), proliferation identity spoofing threats has led to need for constant entity verification devices. Recently, a formal framework been proposed study resistance impersonation attacks One-Message Unilateral Entity Authentication (OM-UEA) schemes, in which prover continuously authenticates itself through use sequence authentication messages. Given limited computing power parties (particularly prover) and often bandwidth channel, IoT scenario it is desirable design unilateral schemes that require single message per session light computations. this paper, we first show OM-UEA can be implemented digital signatures weak form unforgeability sufficient achieve security against active adversaries. We then apply signature scheme by Yang et al. ASIACCS 2020 our framework, resulting an requires minimal computational effort low storage requirements prover. Inspired last construction, propose based on hardness discrete logarithm problem, further improves performance Our findings offer feasible options implementing secure continuous applications.
