Modified Lightweight AES Based Two Level Security Model for Communication on IoT

Abstract

Security provisioning in an extremely heterogeneous environment like Internet of Things (IoT) has been a major challenge for the researchers and scientists around the globe. There are several approaches to network security and cryptographic algorithms entertain relatively higher popularity in the context of network security and inferably for IoT too. Furthermore, implementation of lightweight cryptography is mostly desirable for IoT security considering the fact that IoT encompasses huge number of resource constrained radio frequency driven small devices. In this paper, we have proposed an abstract secure communication model for IoT using lightweight symmetric block cipher AES where a two level security provisioning is implemented.
