Performance Evaluation and Review of Lightweight Cryptography in an Internet-of-Things Environment

Internet-of-Things is used in numerous applications including industrial, military systems and the platform like any other on the internet is vulnerable to security threats. However, due to the nature of the devices used, conventional security methods can incur an overhead and may obstruct the mission of the application due to resource constraints of the devices involved. To alleviate this problem, lightweight cryptographic algorithms have been proposed. Development and implementation of such algorithms continue to move forward; however, it remains a challenge to find suitable algorithms that match the specific needs of the IoT application implementer. In this paper, lightweight cryptography algorithms are categorized, and a few are chosen to be simulated and compared using metrics relevant to an Internet-of-Things environment.
