IRJET-Secure IoT Data using Cryptography Algorithm
0 likes28 views
This document summarizes a research paper that proposes a system to securely transmit Internet of Things (IoT) data from an automated street lighting system using cryptography. The system uses infrared sensors and light dependent resistors to detect vehicles and control street lights. When movement is detected, lights turn on and off as needed. Energy usage data is stored in a database and encrypted using an AES algorithm before being sent to a cloud server for authorized remote access and monitoring of the street lighting system. The system aims to save energy by automating lighting based on presence detection while also securing the IoT data transmission through encryption.

4.Methodology:
Flow chart
Street lights are consuming too much energy so to eliminate that problemwe are using automated street lights. LDR sensor
is use so that lights will get off during daytime and on during night time. It completely eliminate the manual process. In
addition to that at night time whenever the car arrives the lights will get ON and once the car is gone lights will get OFF.
In this way street lights are efficient at night time also. Energy consumed by street lights are store in database. Also the
data is secured by using AES algorithm.
3. CONCLUSIONS
This project “IOT Based Smart Intelligent Lighting System for Smart City “ is a cost effective, practical, eco friendly and the
safest way to save energy and this system the light status information can be accessed from anytime and anywhere. It clearly
tackles the two problems that world is facing today, saving of energy and also disposal of incandescent lamps very efficiently.
Initial cost and maintenance can be the draw backs of this project. The system ensures the security to the people and it
provides a great security exclusively for women.

Project gives solution for electrical power wastage also the manual operation of the lighting system is completely eliminated. The proposed system provide a solution for energy saving. This is achieved by sensing and approachingavehicle using an IR transmitter and IR Receiver couple. Upon sensing the movement the sensor transmit the data to the microcontroller which furthermore the Light to switch ON. Similarly as soon as the vehicle or an obstacle goes away the Light gets switched OFF as the sensor sense any object at the same time the status (ON/OFF) of the street light can be accessed from anywhere and anytime through internet, and after that process we are saving information to the cloud server how muchenergy wassavedfromthestreet and Consumed from the street. After that information we will apply AES Algorithm for data security. Key Words: LDR:Light Dependent Reesistor, LED:Light Emitting Diode, IR:Infrared Sensor. 1.INTRODUCTION In the Project we are focusing on the concept like we need to secure the IOT data and main concept if for the after detect of obstacle the light will be on for the street. The system architecture of the intelligent street light system consists of IR sensors, LDR, Raspberry PI, Relay, UART and Wifi Module. LDR‟s are light dependent devices whose resistance decreases when light falls on them and increases in the dark and detection of the car. When a light dependent resistor is kept in dark, its resistance is very high. The vehicle which passes by the street light is detected by IR sensor.Relayis used as a switch to switch on/off the street light bulb. A UART (Universal Asynchronous Receiver/Transmitter) is the microchip with programming that controls a computer's interface to its attached street light system. After receiving all the information we convert the information in the encryption format for the second userforthedata security.Thatinformationwe will saved in cloud storage only authorized user can access the all information. 1.1 Disadvantages of existing system 1. Manual switching off/on of Street Lights 2. More Energy Consumption. 3. High expense. 4. More manpower. 1.2 Advantages of proposed system 1. We use wireless communication. 2. Completely elimination of man power. 2. Materials: 1 .IR sensor:

The module has on board potentiometer that lets user adjust detection range. The sensor has very good and stable response even in ambient light or in complete darkness. Working Principle of IR Sensor: The IR Sensor has built-in IR transmitter and IR receiver. Infrared Transmitter is a light emitting diode (LED) which emits infrared rays. Hence, they are called IR LED. Even though an IR LED looks like a normal LED, the radiation emitted by IR LED is invisible to the human eye. Infrared receiversare alsocalledasinfraredsensorsastheydetecttheraysfromanIRtransmitter.IR receivers comein the form of photodiodesandphototransistors.InfraredPhotodiodesaredifferentfromnormalphotodiodesas they detect only infrared radiation. When the IR transmitter emits radiation, it reaches the object and some of the radiation reflects back to the IR receiver. Based on the intensity of the reception by the IR receiver, the output of the sensor is defined. 2 .LDR sensor: An light dependent resistor is also known as photo resistor, photocell , photoconductor.It is a one type of resistor whose resistance varies depending on the amount of light falling on its surface When the light falls on the resistor, then the resistance changes. These resistorsare often used in many circuits where it isrequiredtosensethepresenceoflight.Theseresistorshavea variety of functions and resistance. For instance, when the LDR is in darkness, then it can be used to turn ON a light or to turn OFF a light when it is in the light. Working principle of LDR sensor: This resistor works on the principle of photo conductivity. It is nothing but, when the light falls on its surface, then the material conductivity reduces and also the electrons in the valence band of the device are excitedto the conduction band.Thesephotons in the incident light must have energy greater thanthebandgapofthesemiconductormaterial.Thismakestheelectronstojump from the valence band to conduction. These devices depend on the light, when light falls on the LDR then the resistance decreases,and increases in the dark. When a LDR is kept in the dark place, its resistance is high and, when the LDR iskept inthe light its resistance will decrease. 3.Raspberry pi 3B- The Raspberry Pi just got juicer! Now with a Quad-Core 64bit CPU, WiFi & Bluetooth.The Raspberry Pi 3 Model B is the third generation Raspberry Pi. This powerful credit-card sized single board computer can be used for many applications and supersedes the original Raspberry Pi Model B+ and Raspberry Pi 2 Model B. Whilst maintaining the popular board format the Raspberry Pi 3 Model B brings you a more powerful processor, 10x faster than the first generation Raspberry Pi. Additionally it adds wireless LAN & Bluetooth connectivity making it the ideal solution for powerful connected designs. 4.LED It is Light Emitting Diode. To save energy weare using LED .It is alight-emitting diode is a two-lead semiconductor lightsource. It is a p–n junction diode that emits light when activated.
