One time password authentication scheme based on elliptic curves for Internet of Things (IoT)

Abstract

Establishing end-to-end authentication between devices and applications in Internet of Things (IoT) is a challenging task. Due to heterogeneity in terms of devices, topology, communication and different security protocols used in IoT, existing authentication mechanisms are vulnerable to security threats and can disrupt the progress of IoT in realizing Smart City, Smart Home and Smart Infrastructure, etc. To achieve end-to-end authentication between IoT devices/applications, the existing authentication schemes and security protocols require a two-factor authentication mechanism. Therefore, as part of this paper we review the suitability of an authentication scheme based on One Time Password (OTP) for IoT and proposed a scalable, efficient and robust OTP scheme. Our proposed scheme uses the principles of lightweight Identity Based Elliptic Curve Cryptography scheme and Lamport's OTP algorithm. We evaluate analytically and experimentally the performance of our scheme and observe that our scheme with a smaller key size and lesser infrastructure performs on par with the existing OTP schemes without compromising the security level. Our proposed scheme can be implemented in real-time IoT networks and is the right candidate for two-factor authentication among devices, applications and their communications in IoT.

Internet of Things (IoT) of Smart Home: Privacy and Security

“…Other works discuss secure healthcare architecture and communication of nodes in a Constrained Application Protocol (CoAP; an application layer protocol that is prepared for use in Internet devices in IoT smart homes, such as wireless sensor network nodes) network [19], as well as security challenges between heterogeneous devices and different applications in smart homes [7]. Some studies focus on password security and applications for IoT smart home systems [20] [21], secure software updates in smart home devices, and security system devices (e.g., surveillance cameras) and their use in smart homes [22]. Home automation and security threats are also defined, A new solution is presented to address risk reduction in cases of privacy breaches in smart energy management systems [23].…”
