摘要
Purpose-Due to the connectivity of the multiple devices and the systems on the same network,rapid development has become possible in Internet of Things(IoTs)for the last decade.But,IoT is mostly affected with severe security challenges due to the potential vulnerabilities happened through the multiple connectivity of sensors,devices and system.In order to handle the security challenges,literature presents a handful of security protocols for IoT.The purpose of this paper is to present a threat profiling and elliptic curve cryptography(ECC)-based mutual and multi-level authentication for the security of IoTs.This work contains two security attributes like memory and machine-related attributes for maintaining the profile table.Also,the profile table stores the value after encrypting the value with ECC to avoid storage resilience using the proposed protocol.Furthermore,three entities like,IoT device,server and authorization centre(AC)performs the verification based on seven levels mutually to provide the resilience against most of the widely accepted attacks.Finally,DPWSim is utilized for simulation of IoT and verification of proposed protocol to show that the protocol is secure against passive and active attacks.Design/methodology/approach-In this work,the authors have presented a threat profiling and ECC-based mutual and multi-level authentication for the security of IoTs.This work contains two security attributes like memory and machine-related attributes for maintaining the profile table.Also,the profile table stores the value after encrypting the value with ECC to avoid storage resilience using the proposed protocol.Furthermore,three entities like,IoT device,server and AC performs the verification based on seven levels mutually to provide the resilience against most of the widely accepted attacks.Findings-DPWSim is utilized for simulation of IoT and verification of the proposed protocol to show that this protocol is secure against passive and active attacks.Also,attack analysis is carried out to prove the robustness of the proposed protocol against the password guessing attack,impersonation attack,server spoofing attack,stolen verifier attack and reply attack.Originality/value-This paper presents a threat profiling and ECC-based mutual and multi-level authentication for the security of IoTs.
