Light Weight Access Control System for Constrained IOT Devices
ABSTARCT :
This paper presents a low cost and flexible home control and monitoring system using an embedded micro-web server, with IP connectivity for accessing and controlling devices and appliances remotely using Android based Smart phone app. The proposed system does not require a dedicated server PCwith respect to similar systems and offers a novel communication protocol to monitor and control the home environment with more than jus t the s witching functionality. To demonstrate the feasibility and effectiveness of this system, devices such as light switches , power plug, temperature sensor and current sensor have been integrated with the proposed home control system.
EXISTING SYSTEM :
? A lot of applications for smart TV, smart fridge, smart car, network energy monitors, and activity tracking systems now exist in homes as well as at workplaces.
? However, the existing works were mainly focused on switching and controlling home appliances or connected devices rather than remotely monitoring of home environment.
? It is based on existing Internet standards, and Datagram Transport Layer Security (DTLS) protocol, which is placed between transport and application layer.
? Sensors are a low-powered device with memory constraints, and that is why it is hard to implement existing network security solutions in the sensors.
DISADVANTAGE :
? It also provides a better understanding of the interaction of mobile devices and other devices in IoT environment and discusses the problems of having privacy and access control risks.
? To overcome this problem, they proposed an access control method considering the context of the IoT device.
? Although there has been a lot of researches in the area of the access control system in IoT environment, these specifically target the problem of lightweight cyphering in pervasive environments and improving standard protocols.
? The objective is to neutralize the risks arises due to IoT and overcome the problems of traditional authorization and firewall system in IoT environment.
PROPOSED SYSTEM :
• The proposed system does not require a dedicated server PC with respect to similar systems and offers a novel communication protocol to monitor and control the home environment with more than just the switching functionality.
• Home automation using Cloud computing has also been proposed by where users were able to control various lights and appliances within their home.
• This proposed access control architecture can secure IoT sensors as well as protect sensor data.
• A dynamic attribute-based authorization system formed on the device’s contextual information is proposed to ensure a secured interaction between user’s mobile device and IoT sensor nodes.
ADVANTAGE :
• The performance of systems slows down under heavy workloads, resulting in high latency, scalability analysis of cloud was also conducted.
? These smart devices are highly constrained in memory and computational power, these devices have the ability to monitor and collect environment data efficiently.
? These innovative technologies provide assistance to our everyday activities, health support, energy efficiency, security, and comfort.
? Data collection, enabling real-time responses, improving access and control of devices, increasing efficiency and productivity, and connecting technologies are the essential features that could benefit our personal life as well as organizations.
