Comparative Study of Lightweight Cryptographic Algorithms for IoT (original) (raw)

The deployment of IoT facilitates the physical devices with communication, computation and decision making on the basis of any action occurred on network medium. It raises the need of a secured communication channel among different categories of devices. A notable impact has been seen in our day to day life while communicating among smart devices due to the sudden enhancement in ICT technology. IoT enables users to communicate in heterogeneous environment as each user can deploy different way of communication and computation. Thus, this network becomes more prone to attack by a malicious user compromising security and privacy of network. Through the medium of this paper we try to perform indepth study of currently existing security mechanisms for IoT. First, we are comparing lightweight cryptographic mechanisms in concern with key and block sizes, number of rounds and possible attacks. Secondly, we try to discuss various existing security issues with their possible solutions. In a nutshell, a security solution with less computational complexity and less prone to attacks is required.
