Internet of things (IoT) is going to be an integral part of our lives in the next few years. It will be found as direct service provider in our surroundings through the connected sensor based networks. Even indirectly, it will serve us in several forms as value added services over the cellular platforms. However, it is very much vulnerable from several security threats. The current security level is not very strong for the future applications of IoT. There is a need of a robust cryptosystem for IoT. In this article, we propose quantum cryptography as a security solution for IoT in the long term. We explain the motivation behind this idea and the potential applications in IoT in the near future.

INTRODUCTION

Internet of Things (IoT) is an emerging technology which can disrupt the current trends in ICT. Its financial potentials are also huge [1]. It has been proposed as an integral part of connected living. Thus in the next decade, IoT will have ubiquitous presence in the inhabited areas [2]. As it is going to be an important aspect of the lives of people there are several challenges. It will deal with a large amount of sensitive data. These data need appropriate security and integrity. In the current scenarios elliptic curve cryptosystems (ECCs) are the popular choices for IoT security [3]. However, IoT is seen as a long term solution for several applications. In the next few decades the quantum computers are expected to arrive and that will certainly decode all the ECCs quite easily. Therefore, IoT does not have a proper security framework in the long run. That is the main motivation for us to propose quantum cryptography (QC) for IoT as a robust security which can sustain the threats from the quantum computers. In [1], control and management of security in systems is achieved using QC. It depicts the security strength of QC. In [2], some of the recent advances of security framework along with its characteristics are presented. This paper provides relevant questions for the researchers in the fields of quantum optics, quantum information processing and quantum communications. In [3], the practical resource trade-offs are highlighted in the context of QC and related algorithms. In [4], entangled pairs connecting the earth and orbiting satellites are presented which gives the scope for the next generation quantum cryptographic systems at a large scale. In [5], the applications of the quantum theory are depicted for security over the Internet. It addresses the increasing number of research branches associated with QC. It also discusses the protocols which address many real scenarios such as ecommerce. In [6], some of the present experimental accomplishments, future enhancements, ideas and patents on QC are discussed. This work compares the nature of quantum data with the classical data, and highlights the fact that quantum data cannot be read without modifying it. This work also addresses the complexity involved in bringing the quantum machines into the real world. In [7], a fully secure quantum key exchange is demonstrated over a 1.9 km freespace range using the concept of QC. A long-term goal of this work is to illustrate the key exchange to a satellite orbiting at 300 to 1200 km altitude. In [8], the current advancements in China in developing Internet of Things (IoT) are highlighted. It addresses the methodologies; research and development plans for the widespread deployment of IoT. It also depicts a generalized IoT architecture with three platforms to realize the challenging architecture of IoT. In [9], present state-of-the-art of industrial IoT is systematically recapitulated. It introduces the contextual and service oriented architectures of IoT. It also addresses the vital machineries that might be used in IoT. In [10], an overview of IoT is analyzed, emphasizing the need for healthier unification among IoT facilities. Long Term Evolution (LTE) based cellular IoT solutions are emphasized in [11], giving importance to low cost, low power consumption and longer battery life. It also considers the security aspects of IoT. In [12], the impact of IoT on the forthcoming future is analyzed. It also highlights eight prominent research topics on IoT, addressing some of the key research problems. In this article, we present the importance of a reliable security system for IoT. We show that QC is the right choice for the long term security of IoT. In the long run, the currently used techniques will fail. QC can sustain all the foreseeable security threats.
