Overview

There are many emerging areas in which highly constrained devices are interconnected and communicated to accomplish some tasks. Nowadays, Internet of Things (IoT) enables many low resources and constrained devices to communicate, compute process and make decision in the communication network. In the heterogeneous environments for IoT, there are many challenges and issues like power consumption of devices, limited battery, memory space, performance cost, and security in the Information Communication Technology (ICT) network. In this paper, we discuss a state-of-art of lightweight cryptographic primitives which include lightweight block ciphers, hash function, stream ciphers, high performance system, and low resources device for IoT environment in details. We analyze many lightweight cryptographic algorithms based on their key size, block size, number of rounds, and structures. In addition, we discuss the security architecture in IoT for constrained device environment, and focus on research challenges, issues and solutions. Finally, a proposed security scheme with a service scenario for an improvement of resource constrained IoT environment and open issues are discussed.
