Role-Based Identity01:21

Role-Based Identity

80
Role-based identities are central to understanding how individuals navigate social environments by adopting distinct self-conceptions aligned with various societal roles. These identities are not fixed traits but are constructed through personal actions and the social feedback individuals receive in context-specific interactions. Each social role, such as student, teacher, or friend, carries a set of expectations and norms that influence how people think, feel, and behave within that...

Self-Locking Screw01:16

Self-Locking Screw

2.0K
A square-threaded screw jack is a mechanical device widely used for lifting heavy loads or applying considerable force. One of the key features that can make a screw jack more effective and reliable is its self-locking capability.
A square-threaded screw jack carrying a load is considered self-locking if the screw retains its position even after the moment applied to it is removed.

Social Proof

30.5K
Social proof is a form of persuasion based on comparison and conformity. People compare their behavior and actions to what others are doing and will change to conform to do what their peers do.

Ionic Strength: Overview

2.3K
The ionic strength of a solution is a quantitative way of expressing the total electrolyte concentration of a solution. This concept was first introduced in 1921 by two American physical chemists, Gilbert N. Lewis and Merle Randall, while describing the activity coefficient of strong electrolytes. During the calculation of ionic strength (I or μ), all the cations and anions are considered. However, the concentration (c) of an ion with a greater charge number (z) has a greater contribution...

Household Wiring And Electrical Safety

1.4K
Companies that supply power to most modern households use three conductors, typically called a three-wire line. While one is neutral, the other two are both at 120 V but with opposite polarity, giving a voltage of 240 V between them. With a three-wire line, high-power appliances that require 240 V, such as electric stoves and clothes dryers, are linked between the two hot lines. 120 V appliances can be connected between the neutral and either of the hot lines. The neutral side, which is always...

Area of Science:

  • Computer Science
  • Cybersecurity
  • Internet of Things (IoT)

Background:

  • Smart homes offer convenience but face security and privacy risks due to insecure communication channels.
  • Existing authentication protocols, like Xiang and Zheng's (2020), may fail to provide secure mutual authentication and are vulnerable to attacks.
  • A robust authentication mechanism is crucial for secure user and device interaction in smart home environments.

Purpose of the Study:

  • To propose a novel, secure, and lightweight authentication protocol for Internet of Things (IoT)-based smart homes.
  • To address and resolve the identified security flaws in Xiang and Zheng's device authentication protocol.
  • To enhance the security and privacy of smart home environments.

Main Methods:

  • Developed a new authentication protocol designed for IoT-based smart homes.
  • Conducted informal and formal security analyses, including the Real-or-Random (ROR) model and Burrows-Abadi-Needham (BAN) logic.
  • Utilized the Automated Validation of Internet Security Protocols and Applications (AVISPA) tool for formal verification.
  • Performed comparative analysis of security and performance properties against existing protocols.

Main Results:

  • The proposed protocol effectively resolves security vulnerabilities such as stolen smart device, impersonation, and session key disclosure.
  • Demonstrated secure mutual authentication between users and smart devices.
  • Achieved lower computational costs compared to existing authentication protocols.
  • Validation through ROR model, BAN logic, and AVISPA confirmed the protocol's security.

Conclusions:

  • The proposed authentication protocol offers enhanced security and privacy for IoT-based smart homes.
  • It provides a more secure alternative to existing protocols, with reduced computational overhead.
  • The protocol is suitable for practical implementation in smart home environments, ensuring reliable device authentication.
