Strong Unilateral Authentication of Low-cost Devices Involved in Internet of Things in Smart Homes

Abstract

In this paper we focused on authentication of low-cost devices involved in Internet of Things (IoT) in smart homes. We proposed a unilateral authentication protocol for authentication of low-cost devices involved in IoT with a Control Unit (CU) of a smart house. The protocol allows secure transmission of secret information between communication entities. Only cryptographic primitives as Hash functions, XOR operations and Physical unclonable functions (PUFs) are necessary for execution of the protocol. Security of the proposed protocol is described.
