  Industrial IoT (IIoT) aims to enhance services provided by various industries
such as manufacturing and product processing. IIoT suffers from various
challenges and security is one of the key challenge among those challenges.
Authentication and access control are two notable challenges for any Industrial
IoT (IIoT) based industrial deployment. Any IoT based Industry 4.0 enterprise
designs networks between hundreds of tiny devices such as sensors, actuators,
fog devices and gateways. Thus, articulating a secure authentication protocol
between sensing devices or a sensing device and user devices is an essential
step in IoT security. In this paper, first, we present cryptanalysis for the
certificate-based scheme proposed for similar environment by Das et al. and
prove that their scheme is vulnerable to various traditional attacks such as
device anonymity, MITM, and DoS. We then put forward an inter-device
authentication scheme using an ECC (Elliptic Curve Cryptography) that is highly
secure and lightweight compared to other schemes for a similar environment.
Furthermore, we set forth a formal security analysis using the random oracle
based ROR model and informal security analysis over the Doleve-Yao channel. In
this paper, we present the comparison of the proposed scheme with existing
schemes based on communication cost, computation cost and security index to
prove that the proposed EBAKE-SE is highly efficient, reliable, and trustworthy
compared to other existing schemes for inter-device authentication. At long
last, we present an implementation for the proposed EBAKE-SE using MQTT
protocol
