Lightweight cryptography algorithms for internet of things enabled networks: An overview

Abstract

Internet of Things is a worldwide set-up of interconnected entities that permits millions of devices to communicate with each other. Combined with reliable communication, ensuring security concerning confidentiality, integrity, and authenticity is a great challenge in IoT. Unsecured IoT devices open gateway for attacks. Unprotected and vulnerable devices, at times, allow easy entry for hackers, enabling them to have access to the shared network and personal, corporate assets. Conventional security measures are not suitable and cannot be applied to IoT technologies because of their minimum storage, low processing capacity, and limited computing power. Besides, scalability and heterogeneity issues arise when a variety of devices are interconnected. This paper presents the security threats and requirements of IoT cryptography, technology, and trends. The paper also discusses the challenges faced and the comparison of solutions already existing in IoT security.
